Sino-Roman relations comprised the (primarily indirect) contacts and flows of trade goods, information, and occasional travelers between the Roman Empire and the Han dynasty, as well as between the later Eastern Roman Empire and various successive Chinese dynasties that followed. These empires inched progressively closer to each other in the course of the Roman expansion into ancient Western Asia and of the simultaneous Han military incursionsinto Central Asia. Mutual awareness remained low, and firm knowledge about each other was limited. Surviving records document only a few attempts at direct contact. Intermediate empires such as the Parthians and Kushans, seeking to maintain control over the lucrative silk trade, inhibited direct contact between the two ancient Eurasian powers. In 97 AD, the Chinese general Ban Chao tried to send his envoy Gan Ying to Rome, but Parthians dissuaded Gan from venturing beyond the Persian Gulf. Ancient Chinese historians recorded several alleged Roman emissaries to China. The first one on record, supposedly either from the Roman emperor Antoninus Pius or from his adopted son Marcus Aurelius, arrived in 166 AD. Others are recorded as arriving in 226 and 284 AD, followed by a long hiatus until the first recorded Byzantine embassy in 643 AD.
The indirect exchange of goods on land along the Silk Road and sea routes involved (for example) Chinese silk, Roman glassware and high-quality cloth. Roman coins minted from the 1st century AD onwards have been found in China, as well as a coin of Maximian (Roman emperor from 286 to 305 AD) and medallions from the reigns of Antoninus Pius (r. 138–161 AD) and Marcus Aurelius (r. 161–180 AD) in Jiaozhi (in present-day Vietnam), the same region at which Chinese sources claim the Romans first landed. Roman glassware and silverware have been discovered at Chinese archaeological sites dated to the Han period (202 BC to 220 AD). Roman coins and glass beads have also been found in the Japanese archipelago. (Full article...)
Holotype skull shown from above (A), the right side (B), and below (C)
Xixiasaurus (/ˌʃiːʃiəˈsɔːrəs/) is a genus of troodontiddinosaur that lived during the Late CretaceousPeriod in what is now China. The only known specimen was discovered in Xixia County, Henan Province, in central China, and became the holotype of the new genus and speciesXixiasaurus henanensis in 2010. The names refer to the areas of discovery, and can be translated as "Henan Xixia lizard". The specimen consists of an almost complete skull (except for the hindmost portion), part of the lower jaw, and teeth, as well as a partial right forelimb.
Xixiasaurus is estimated to have been 1.5 metres (5 ft) long and to have weighed 8 kilograms (18 lb). As a troodontid, it would have been bird-like and lightly built, with grasping hands and an enlarged sickle-shaped claw on the second toe. Its skull was long, with a long, low snout that formed a tapering U-shape when seen from below. The frontal bone of the forehead was dome-like in side view, which indicates it had an enlarged braincase. It differed from other troodontids in that the front of the dentary bone of the lower jaw was down-turned. Unlike in most troodontids, the teeth of Xixiasaurus did not have serrations; instead, their carinae (front and back edges) were smooth and sharp. It was distinct among troodontids in having 22 teeth in each maxilla (in other genera the maxillary tooth count was either higher or lower). (Full article...)

Luo Yixiu (Chinese: 羅一秀; 20 October 1889 – 11 February 1910), a Han Chinese woman, was the first wife of the later Chinese communist revolutionary and political leader Mao Zedong, to whom she was married from 1908 until her death. Coming from the area around Shaoshan, Hunan, in south central China – the same region as Mao – her family were impoverished local landowners.
Most of what is known about their marriage comes from an account Mao gave to the American reporter Edgar Snow in 1936, which Snow included in his book Red Star Over China. According to Mao, he and Luo Yixiu were the subject of an arranged marriage organised by their respective fathers, Mao Yichang and Luo Helou. Luo was eighteen and Mao just fourteen years old at the time of their betrothal. Although Mao took part in the wedding ceremony, he later said that he was unhappy with the marriage, never consummating it and refusing to live with his wife. Socially disgraced, she lived with Mao's parents for two years until she died of dysentery, while he moved out of the village to continue his studies elsewhere, eventually becoming a founding member of the Chinese Communist Party. Various biographers have suggested that Mao's experience of this marriage affected his later views, leading him to become a critic of arranged marriage and a vocal feminist. He married three more times, to Yang Kaihui, He Zizhen and Jiang Qing, the last of whom was better known as Madame Mao. (Full article...)

Peking opera in Shanghai, 2014
Peking opera, or Beijing opera (Chinese: 京劇; pinyin: Jīngjù), is the most dominant form of Chinese opera, which combines instrumental music, vocal performance, mime, martial arts, dance and acrobatics. It arose in Beijing in the mid-Qing dynasty (1644–1912) and became fully developed and recognized by the mid-19th century. The form was extremely popular in the Qing court and has come to be regarded as one of the cultural treasures of China. Major performance troupes are based in Beijing, Tianjin and Shanghai. The art form is also preserved in Taiwan, where it is also known as Guójù (Chinese: 國劇; lit. 'National opera'). It has also spread to other regions such as the United States and Japan.
Peking opera features four main role types, sheng (gentlemen), dan (women), jing (rough men), and chou (clowns). Performing troupes often have several of each variety, as well as numerous secondary and tertiary performers. With their elaborate and colorful costumes, performers are the only focal points on Peking opera characteristically sparse stage. They use the skills of speech, song, dance and combat in movements that are symbolic and suggestive, rather than realistic. Above all else, the skill of performers is evaluated according to the beauty of their movements. Performers also adhere to a variety of stylistic conventions that help audiences navigate the plot of the production. The layers of meaning within each movement must be expressed in time with music. The music of Peking opera can be divided into the xīpí (西皮) and èrhuáng (二黄) styles. Melodies include arias, fixed-tune melodies and percussion patterns. The repertoire of Peking opera includes over 1,400 works, which are based on Chinese history, folklore and, increasingly, contemporary life. (Full article...)
In his Dream Pool Essays or Dream Torrent Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187). Shen discovered the concept of true north in terms of magnetic declination towards the north pole, with experimentation of suspended magnetic needles and "the improved meridian determined by Shen's [astronomical] measurement of the distance between the pole star and true north". This was the decisive step in human history to make compasses more useful for navigation, and may have been a concept unknown in Europe for another four hundred years (evidence of German sundials made circa 1450 show markings similar to Chinese geomancers' compasses in regard to declination).

Despite support from linguists both in China and overseas—including some early proponents who hoped it would eventually replace Chinese characters altogether—GR never achieved widespread use among the Chinese public, who generally lacked interest in the system or viewed it with hostility due to its complex spelling rules. In places where GR had gained traction, it was eventually replaced—largely by Hanyu Pinyin (or simply "pinyin"), which became the international standard during the 1980s, and itself follows principles originally introduced by GR. Widespread adoption of the system was also hindered by its narrow calibration to the Beijing dialect, during a period when China lacked the strong central government needed to impose use of a national spoken language.

The empire in 661, when it reached its greatest extent
The Li family founded the dynasty after taking advantage of a period of Sui decline and precipitating their final collapse, in turn inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The An Lushan rebellion (755–763) led to devastation and the decline of central authority during the latter half of the dynasty. Like the previous Sui dynasty, the Tang maintained a civil-service system by recruiting scholar-officials through standardised examinations and recommendations to office. The rise of regional military governors known as jiedushi during the 9th century undermined this civil order. The dynasty and central government went into decline by the latter half of the 9th century; agrarian rebellions resulted in mass population loss and displacement, widespread poverty, and further government dysfunction that ultimately ended the dynasty in 907.

After the Chinese Communist Revolution, the Party sought to memorialize their achievements through artworks. Dong was commissioned to create a visual representation of the October 1 ceremony, which he had attended. He viewed it as essential that the painting show both the people and their leaders. After working for three months, he completed an oil painting in a folk art style, drawing upon Chinese art history for the contemporary subject. The success of the painting was assured when Mao viewed it and liked it, and it was reproduced in large numbers for display in the home. (Full article...)

A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon.
The word cannon is derived from several languages, in which the original definition can usually be translated as tube, cane, or reed. In the modern era, the term cannon has fallen into decline, replaced by guns or artillery, if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons.

Hu lived in Nanjing during the transition from the Ming dynasty to the Qing dynasty. A Ming loyalist, he was offered a position at the rump court of the Hongguang Emperor, but declined the post, and never held anything more than minor political office. He did, however, design the Hongguang Emperor's personal seal, and his loyalty to the dynasty was such that he largely retired from society after the emperor's capture and death in 1645. He owned and operated an academic publishing house called the Ten Bamboo Studio, in which he practised various multi-colour printing and embossing techniques, and he employed several members of his family in this enterprise. Hu's work at the Ten Bamboo Studio pioneered new techniques in colour printmaking, leading to delicate gradations of colour which were not previously achievable in this art form. (Full article...)

The Battle of Caishi (Chinese: 采石之戰) was a major naval engagement of the Jin–Song Wars of China that took place on November 26–27, 1161. It ended with a decisive Song victory, aided by their use of gunpowder weapons.
Both in its lyrics and instruments, the song mixes traditional Chinese styles with modern rock elements. In the lyrics, the speaker addresses a girl who is scorning him because he has nothing. However, the song has also been interpreted as being about the dispossessed youth of the time, because it evokes a sense of disillusionment and lack of individual freedom that was common among the young generation during the 1980s.

Lactarius indigo, commonly known as the indigo milk cap, indigo milky, indigo lactarius, blue lactarius, or blue milk mushroom, is a species of agaric fungus in the family Russulaceae.
The fruit body color ranges from dark blue in fresh specimens to pale blue-gray in older ones. The milk, or latex, that oozes when the mushroom tissue is cut or broken (a feature common to all members of the genus Lactarius) is also indigo blue, but slowly turns green upon exposure to air. The cap has a diameter of 5–15 cm (2–6 in), and the stem is 2–8 cm (3⁄4–3+1⁄8 in) tall and 1–2.5 cm (3⁄8–1 in) thick. (Full article...)
The modern Chinese varieties make frequent use of what are called classifiers or measure words. One use of classifiers is when a noun is qualified by a numeral or demonstrative. In the Chinese equivalent of a phrase such as "three books" or "that person", it is normally necessary to insert an appropriate classifier between the numeral/demonstrative and the noun. For example, in Standard Chinese, the first of these phrases would be: (Full article...)

Henan or Yu cuisine is an umbrella term used to define the native cooking styles of the Henan province in China. Henan (河南, or Honan) is a province located in Central China and is often also referred to by the names Zhongzhou or Zhongyuan, which means ‘midland’. Being landlocked on all sides, the influence of localized culinary styles are plentiful to be observed in Henan cuisine. It incorporates a blend of culinary styles from Jiangsu and Beijing, which gives it a unique mix of taste. Henan cuisine is well known for its taste variety including a blend of sour, sweet, bitter, spicy and salty. There are a wide variety of Henan dishes, including carp with fried noodles in sweet and sour sauce, grilled head and tail of black carp, Bianjing roasted duck, stewed noodles with mutton, and spicy soup. Despite its mix of flavours within its culinary forms, Henan cuisine is not known to take them to the extreme. Rather, Henan cuisine is known for inducing a very moderate and balanced mix of flavours in its dishes. Henan has a long cultural history, which not only left precious cultural relics and historical sites but also Henan cuisine. Henan cuisine, has the honor of being one of China's oldest and most traditional cooking styles. There are more than 50 kinds of cooking methods in preparing Henan cuisine. The history of the province shows its relation to the affinity towards food culture among the people of Henan, where the motive to bring together the different tastes from the north and the south to blend it into one dish.

The 2019 World Open (also known as the 2019 Yushan World Open) was a professional snooker tournament that took place between 28 October and 3 November 2019 at the Yushan Sport Centre in Yushan, China. This was the 2019 edition of the World Open, which was first held in 1982. It was the fifth ranking event of the 2019–20 season and the third tournament of the season to be held in China. It would also be the last professional snooker tournament held in mainland China for almost four years, due to the impact of the COVID-19 pandemic. The event featured a prize fund of £772,000 with the winner receiving £150,000.
Shinan District (Chinese: 市南区; pinyin: Shìnán Qū; lit. 'South City District') is an urban district of Qingdao, Shandong. It has an area of 30.01 square kilometres (7,420 acres; 11.59 sq mi), and had approximately 588,800 inhabitants as of 2019. Shinan is located in coastal hilled terrain, and has a temperate monsoon climate. Common features include moderate temperatures, moist air, abundant rainfall, and four distinct seasons. It is notable for its early 20th-century German architecture, unusual in Chinese cities.
In the mid-19th century the European powers forcibly opened China to foreign trade. Germany acquired the Kiautschou Bay concession from China in 1898, and substantially developed a fishing village they spelled "Tsingtao" (simplified Chinese: 青岛; traditional Chinese: 青島; pinyin: Qīngdǎo). The area built by the Germans falls into the part of Qingdao known today as Shinan District. (Full article...)

Tang's campaigns against Western Turks
The conquest of the Western Turks, known as the Western Tujue in Chinese sources, was a military campaign in 655–657 led by the Tang dynasty generals Su Dingfang and Cheng Zhijie against the Western Turkic Khaganate ruled by Ashina Helu. The Tang campaigns against the Western Turks began in 640 with the annexation of the Tarim Basin oasis state Gaochang, an ally of the Western Turks. Several of the oasis states had once been vassals of the Tang dynasty, but switched their allegiance to the Western Turks when they grew suspicious of the military ambitions of the Tang. Tang expansion into Central Asia continued with the conquest of Karasahr in 644 and Kucha in 648. Cheng Zhijie commanded the first foray against the West Tujue, and in 657 Su Dingfang commanded the main army dispatched against the Western Turks, while the Turkic generals Ashina Mishe and Ashina Buzhen led the side divisions. The Tang troops were reinforced by cavalry supplied by the Uyghurs, a tribe that had been allied with the Tang since their support for the Uyghur revolt against the Xueyantuo. Su Dingfang's army defeated Helu at the battle of Irtysh River.
The victory strengthened Tang control of the Western Regions, now modern Xinjiang, and brought the regions formerly ruled by the Khaganate into the Tang empire. Puppet qaghans, the Turkic title for ruler, and military garrisons were installed to administer the newly acquired territories. The Tang dynasty achieved its maximum territorial extent as its western borders reached the eastern frontier of the Umayyad Caliphate. Later on, Turkic revolts ended Tang hegemony beyond the Pamir Mountains in modern Tajikistan and Afghanistan, but a Tang military presence remained in Dzungaria and the Tarim Basin. Central Asia absorbed cultural influences from the conflict. Turkic culture and language spread into Central Asia, as did artistic and political influences from the Tang dynasty. Many of the Tang generals and soldiers stationed in the region were ethnically Turkic, and the prevalence of Indo-European languages in Central Asia declined with acceleration of Turkic migration. The Turks, Tibetans, and the Tang competed for control over Central Asia for the next few centuries. (Full article...)

The second phase of the Expedition began in January 1928, when Chiang resumed command. By April 1928, the nationalist forces had advanced to the Yellow River. With the assistance of allied warlords, including Yan Xishan and Feng Yuxiang, nationalist forces secured a series of decisive victories against the Beiyang Army. As they approached Beijing, Zhang Zuolin, leader of the Manchuria-based Fengtian clique, was forced to flee, and was assassinated shortly thereafter by the Japanese. His son, Zhang Xueliang, took over as the leader of the Fengtian clique, and in December 1928, announced that Manchuria would accept the authority of the nationalist government in Nanjing. With the final piece of China under KMT control, the Northern Expedition concluded successfully and China was reunified, heralding the start of the Nanjing decade. (Full article...)
Hoping to repeat the success of the earlier First Phase Campaign, the PVA 13th Army first launched a series of surprise attacks along the Ch'ongch'on River Valley on the night of November 25, 1950, at the western half of the Second Phase Campaign (Chinese: 第二次战役西线; pinyin: Dì'èrcì Zhànyì Xīxiàn), effectively destroying the Eighth United States Army's right flank, while allowing PVA forces to move rapidly into UN rear areas. In the subsequent battles and withdrawals from November 26 to December 2, 1950, although the Eighth Army managed to avoid being surrounded by PVA forces, the PVA 8th Army were still able to inflict heavy losses onto the retreating UN forces, which had lost all cohesion. In the aftermath of the battle, the Eighth Army's heavy losses forced all UN forces to retreat from North Korea to the 38th Parallel. (Full article...)

Xi'an City Wall
The fortifications of Xi'an (Chinese: 西安城墙), also known as Xi'an City Wall, in Xi'an, represent one of the oldest, largest and best preserved Chinese city walls. It was built under the rule of the Hongwu Emperor Zhu Yuanzhang as a military defense system. It exhibits the "complete features of the rampart architecture of feudal society". It has been refurbished many times since it was built in the 14th century, thrice at intervals of about 200 years in the later half of the 1500s and 1700s, and in recent years in 1983. The wall encloses an area of about 14 square kilometres (5.4 sq mi).
The Xi'an City Wall is on the tentative list of UNESCO's World Heritage Site under the title "City Walls of the Ming and Qing Dynasties". Since 2008, it is also on the list of the State Administration of Cultural Heritage of the People's Republic of China. Since March 1961, the Xi'an City Wall is a heritage National Historical and Cultural Unit. (Full article...)

The Chinese alligator (Alligator sinensis; simplified Chinese: 鼍; traditional Chinese: 鼉; pinyin: tuó), also known as the Yangtze alligator (simplified Chinese: 扬子鳄; traditional Chinese: 揚子鱷; pinyin: yángzǐ'è), China alligator, or historically the muddy dragon, is a crocodilianendemic to China. It and the American alligator (A. mississippiensis) are the only living species in the genusAlligator of the family Alligatoridae. Dark gray or black in color with a fully armored body, the Chinese alligator grows to 1.5–2.1 metres (5–7 ft) in length and weighs 36–45 kilograms (80–100 lb) as an adult. It brumates in burrows in winter and is nocturnal in summer. Mating occurs in early summer, with females most commonly producing 20–30 eggs, which are smaller than those of any other crocodilian. The species is an opportunistic feeder, primarily eating fish and invertebrates. A vocal species, adults bellow during the mating season and young vocalize to communicate with their parents and other juveniles. Captive specimens have reached age 70, and wild specimens can live past 50.
Living in bodies of fresh water, the Chinese alligator's range is restricted to six regions in the province of Anhui, as well as possibly the provinces of Jiangsu and Zhejiang. Originally living as far away from its current range as Japan, the species previously had a wide range and population, but beginning in 6000 BC, multiple threats, such as habitat destruction, caused the species' population and range to decline. The population in the wild was about 1,000 in the 1970s, decreased to below 130 in 2001, and grew after 2003, with its population being about 300 as of 2017. Listed as critically endangered by the International Union for Conservation of Nature, multiple conservation actions have been taking place for this species. (Full article...)
By the late 1980s, the walled city contained roughly 35,000 residents within its territory of 2.6 hectares (6.4 acres; 26,000 m2). As a result of the absence of any widely recognized bureaucracy, the city's residents and businesses had no municipal codes to govern them. Enabled by the enclave's anarchic nature, trade in banned products thrived, ranging from narcotics to dog meat. From the 1950s to the 1970s, it was controlled by local triad gangs and had high rates of prostitution, gambling, and drug abuse. (Full article...)

The 1461 Rebellion of Cao Qin, which broke out within the Inner City of Beijing, threatened the gates of the Imperial City, which contained the imperial family's residence of the Forbidden City (shown here) at its center.
The Rebellion of Cao Qin (simplified Chinese: 曹钦之变; traditional Chinese: 曹欽之變; pinyin: Cáoshí Zhī Biàn) was a day-long uprising in the Ming dynasty capital of Beijing on August7, 1461, staged by Chinese general Cao Qin (曹欽; died 1461) and his Ming troops of Mongol and Han descent against the Tianshun Emperor (r. 1457–1464). Cao and his officers launched the insurrection out of fear of being persecuted by Tianshun. Tianshun had just gained back the throne from his half-brother the Jingtai Emperor, who rose to power during the 1449 Tumu Crisis.
The rebellion was a failure: three of Cao's brothers were killed during the ensuing battle, and Cao Qin was forced to commit suicide during a last stand against imperial troops storming his Beijing residential compound. The rebellion marked the high point in political tension over allowing Mongols to be employed in the Ming military command structure. Ming Chinese officials often made recompense with Mongol subordinates for military merits while at the same time strategically relocating their troops and families away from the capital.

Lhasa is a prefecture-level city, one of the main administrative divisions of the Tibet Autonomous Region of China. It covers an area of 29,274 square kilometres (11,303 sq mi) of rugged and sparsely populated terrain. Its urban center is Lhasa, with around 300,000 residents, which mostly corresponds with the administrative Chengguan District, while its suburbs extend into Doilungdêqên District and Dagzê District. The consolidated prefecture-level city contains additional five, mostly rural, counties.
The city boundaries roughly correspond to the basin of the Lhasa River, a major tributary of the Yarlung Tsangpo River. It lies on the Lhasa terrane, the last unit of crust to accrete to the Eurasian plate before the continent of India collided with Asia about 50 million years ago and pushed up the Himalayas. The terrain is high, contains a complex pattern of faults and is tectonically active. The temperature is generally warm in summer and rises above freezing on sunny days in winter. Most of the rain falls in summer. The upland areas and northern grasslands are used for grazing yaks, sheep and goats, while the river valleys support agriculture with crops such as barley, wheat and vegetables. Wildlife is not abundant, but includes the rare snow leopard and black-necked crane. Mining has caused some environmental problems. (Full article...)
He Siyuan (Chinese: 何思源; Wade–Giles: Ho Ssu-yüan; 1896 – April 1982), also spelled Ho Shih-yuan, was a Chinese educator, politician and guerrilla leader. Educated in China, the United States, and France, he was an economics professor at Sun Yat-sen University and education minister of Shandong Province. When Japan invaded China in 1937, he organized a guerrilla force to fight the resistance war in Shandong, and was the wartime governor of the province. He later became Mayor of Beijing until he negotiated to surrender to communist forces when KMT was losing. He survived Chiang's two attempts to assassinate him, but lost his youngest daughter in the second attack. In 1949 he negotiated the peaceful surrender of Beijing to the Communist forces, ensuring the safety of its millions of residents. Fluent in four European languages, after 1949 he mainly worked on translating foreign publications into Chinese. His elder daughter, He Luli, grew up to become Vice-Mayor of Beijing and Chairwoman of the Revolutionary Committee of the Chinese Kuomintang. (Full article...)

There were great innovations in metallurgy. In addition to Zhou-era China's (c. 1046 – 256 BCE) previous inventions of the blast furnace and cupola furnace to make pig iron and cast iron, respectively, the Han period saw the development of steel and wrought iron by use of the finery forge and puddling process. With the drilling of deep boreholes into the earth, the Chinese used not only derricks to lift brine up to the surface to be boiled into salt, but also set up bamboo-crafted pipeline transport systems which brought natural gas as fuel to the furnaces. Smelting techniques were enhanced with inventions such as the waterwheel-powered bellows; the resulting widespread distribution of iron tools facilitated the growth of agriculture. For tilling the soil and planting straight rows of crops, the improved heavy-moldboard plough with three iron plowshares and sturdy multiple-tube iron seed drill were invented in the Han, which greatly enhanced production yields and thus sustained population growth. The method of supplying irrigation ditches with water was improved with the invention of the mechanical chain pump powered by the rotation of a waterwheel or draft animals, which could transport irrigation water up elevated terrains. The waterwheel was also used for operating trip hammers in pounding grain and in rotating the metal rings of the mechanical-driven astronomical armillary sphere representing the celestial sphere around the Earth.
