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.

Soldiers under the command of Wanyan Liang, the emperor of the Jurchen-led Jin dynasty, tried to cross the Yangzi River to attack the Southern Song dynasty. (Full article...)

Phallus indusiatus, commonly called the basket stinkhorn, bamboo mushrooms, bamboo pith, long net stinkhorn, crinoline stinkhorn, bridal veil, or veiled lady, is a fungus in the family Phallaceae, or stinkhorns. It has a cosmopolitan distribution in tropical areas, and is found in southern Asia, Africa, the Americas, and Australia, where it grows in woodlands and gardens in rich soil and well-rotted woody material. The fruit body of the fungus is characterised by a conical to bell-shaped cap on a stalk and a delicate lacy "skirt", or indusium, that hangs from beneath the cap and reaches nearly to the ground. First described scientifically in 1798 by French botanist Étienne Pierre Ventenat, the species has often been referred to a separate genus Dictyophora along with other Phallus species featuring an indusium. P. indusiatus can be distinguished from other similar species by differences in distribution, size, color, and indusium length.

Mature fruit bodies are up to 25 centimetres (10 inches) tall with a conical to bell-shaped cap that is 1.5–4 cm (1⁄2–1+1⁄2 in) wide. The cap is covered with a greenish-brown spore-containing slime, which attracts flies and other insects that eat the spores and disperse them. An edible mushroom featured as an ingredient in Chinese haute cuisine, it is used in stir-fries and chicken soups. The mushroom, grown commercially and commonly sold in Asian markets, is rich in protein, carbohydrates, and dietary fiber. The mushroom also contains various bioactive compounds, and has antioxidant and antimicrobial properties. P. indusiatus has a recorded history of use in Chinese medicine extending back to the 7th century CE, and features in Nigerian folklore. (Full article...)

Shen Kuo (Chinese: 沈括; 1031–1095) or Shen Gua, courtesy name Cunzhong (存中) and pseudonym Mengqi (now usually given as Mengxi) Weng (夢溪翁), was a Chinese polymath, scientist, and statesman of the Song dynasty (960–1279). Shen was a master in many fields of study including mathematics, optics, and horology. In his career as a civil servant, he became a finance minister, governmental state inspector, head official for the Bureau of Astronomy in the Song court, Assistant Minister of Imperial Hospitality, and also served as an academic chancellor. At court his political allegiance was to the Reformist faction known as the New Policies Group, headed by Chancellor Wang Anshi (1021–1085).

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).

Nathu La(Tibetan: རྣ་ཐོས་ལ་, Wylie: Rna thos la, THL: Na tö la, Sikkimese: རྣ་ཐོས་ལ་) is a mountain pass in the Dongkya Range of the Himalayas between China's Yadong County in Tibet, and the Indian states of Sikkim. But minor touch of Bengal in South Asia. The pass, at 4,310 m (14,140 ft), connects the towns of Kalimpong and Gangtok to the villages and towns of the lower Chumbi Valley.

The pass was surveyed by J. W. Edgar in 1873, who described the pass as being used for trade by Tibetans. Francis Younghusband used the pass in 1903–04, as did a diplomatic British delegation to Lhasa in 1936–37, and Ernst Schäfer in 1938–39. In the 1950s, trade in the Kingdom of Sikkim used this pass. Diplomatically sealed by China and India after the 1962 Sino-Indian War, the pass saw skirmishes between the two countries in coming years, including the clashes in 1967 which resulted in fatalities on both sides. Nathu La has often been compared to Jelep La, a mountain pass situated at a distance of 3 miles (4.8 km). (Full article...)

A series of violent riots over several days broke out on 5 July 2009 in Ürümqi, the capital city of the Xinjiang Uyghur Autonomous Region (XUAR), in northwestern China. The first day's rioting, which involved at least 1,000 Uyghurs, began as a protest, but escalated into violent attacks that mainly targeted Han people. According to Chinese state media, a total of 197 people died, most of whom were Han people or non-Muslim minorities, with 1,721 others injured and many vehicles and buildings destroyed. Many Uyghurs disappeared during wide-scale police sweeps in the days following the riots; Human Rights Watch (HRW) documented 43 cases and said figures for real disappearances were likely to be much higher.

Rioting began following the Shaoguan incident, where false accusations of rape of a Han woman by Uyghur men led to a brawl between ethnic Han and Uyghur factory workers in Shaoguan, resulting in the deaths of two Uyghurs who were both from Xinjiang. The Chinese government claimed that the riots were planned from abroad by the World Uyghur Congress (WUC) and its leader Rebiya Kadeer. Kadeer denies fomenting the violence in her fight for Uyghur self-determination. (Full article...)

The Tang dynasty (/tɑːŋ/, [tʰǎŋ]; Chinese: 唐朝), or the Tang Empire, was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty.

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 devastating An Lushan Rebellion (755–763) shook the nation and led to the decline of central authority in the dynasty's latter half. Like the previous Sui dynasty, the Tang maintained a civil-service system by recruiting scholar-officials through standardized 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.

The women's road race was one of the cycling events at the 2008 Summer Olympics in Beijing, China. It took place on 10 August 2008, featuring 66 women from 33 countries. It was the seventh appearance of an Olympic women's road race event and featured a longer course than any of the previous six races. The race was run on the Urban Road Cycling Course (one of Beijing's nine temporary venues), which is 102.6 kilometres (63.8 mi) total. Including a second lap around the 23.8 km (14.8 mi) final circuit, the total distance of the women's race was 126.4 km (78.5 mi), less than half the length of the men's race.

Heavy rain during most of the race made conditions difficult for the competitors. A group of five broke away during the final lap and worked together until the final sprint, where Nicole Cooke won the race. Cooke earned Great Britain's first medal at these Games and 200th Olympic gold medal overall. Emma Johansson of Sweden and Tatiana Guderzo of Italy, finishing second and third place with the same time as Cooke, received silver and bronze medals respectively. (Full article...)

St. Michael's Cathedral (Chinese: 圣弥爱尔大教堂; pinyin: Shèng Mí'ài'ěr Dàjiàotáng; German: Kathedrale St. Michael), also called the Zhejiang Road Catholic Church (Chinese: 浙江路天主教堂), is a Catholic church in Qingdao (Tsingtao), Shandong Province, China and is the seat of the Bishop of the Diocese of Qingdao (Tsingtao). It is located in the oldest part of Qingdao, at 15 Zhejiang Road, on the east side of Zhongshan Road in Shinan District. Built by German missionaries, the cathedral stands at the top of a hill in the center of the old German-built part of the city. It is the largest example of Romanesque Revival architecture in the province, resembling a German cathedral of the 12th century.

St. Michael's Cathedral is the product of a strong German presence in Shandong Province in the 19th and early 20th centuries. In the mid-19th century the European powers forcibly opened China to foreign trade. The Divine Word Missionaries built a church in the Jiaozhou Bay concession in Shandong in 1902, and in 1934 erected the cathedral, which remained nominally under their administration until 1964. In 1942 it came under the control of the Japanese Army, returning to Chinese control when the Japanese left Qingdao in 1945. In the early 1950s, all foreign missionaries, including the Bishop of Qingdao, were either imprisoned or expelled from China, and during the Cultural Revolution (1966–1976) the cathedral was defaced and abandoned. In 1981, it was repaired by the government and reopened for services, and in 1992 it was listed as a Provincial Historic Building by the government of Shandong Province. (Full article...)

The Han dynasty (UK: /ˈhæn/, US: /ˈhɑːn/; traditional Chinese: 漢朝; simplified Chinese: 汉朝; pinyin: Hàncháo) was an imperial dynasty of China (202 BC – 9 AD, 25–220 AD), established by Liu Bang and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–207 BC) and a warring interregnum known as the Chu–Han contention (206–202 BC), and it was succeeded by the Three Kingdoms period (220–280 AD). The dynasty was briefly interrupted by the Xin dynasty (9–23 AD) established by usurping regent Wang Mang, and is thus separated into two periods—the Western Han (202 BC – 9 AD) and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and it has influenced the identity of the Chinese civilization ever since. Modern China's majority ethnic group refer to themselves as the "Han people" or "Han Chinese". The spoken Sinitic language and written Chinese are referred to respectively as the "Han language" and "Han characters".

The emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the scholarly gentry class. The Han Empire was divided into areas directly controlled by the central government called commanderies, as well as a number of semi-autonomous kingdoms. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States. From the reign of Emperor Wu (r. 141–87 BC) onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in 1912. (Full article...)

Cai Lun (Chinese: 蔡伦; courtesy name: Jingzhong (敬仲); c. 50–62 – 121 CE), formerly romanized as Ts'ai Lun, was a Chinese eunuch court official of the Eastern Han dynasty. He occupies a pivotal place in the history of paper due to his addition of pulp via tree bark and hemp ends which resulted in the large-scale manufacture and worldwide spread of paper. Although traditionally regarded as the inventor of paper, earlier forms of paper have existed since the 3rd century BCE, so Cai's contributions are limited to innovation, rather than invention.

Born in Guiyang Commandery [zh] (in what is now Leiyang), Cai arrived at the imperial court in Luoyang by 75 CE, where he served as a chamberlain for Emperor Ming, and then as Xiao Huangmen, an imperial messenger for Emperor Zhang. To assist Lady Dou in securing her adopted son as designated heir, he interrogated Consort Song and her sister, who then killed themselves. When Emperor He ascended the throne in 88 CE, Dou awarded Cai with two positions: Zhongchang shi [zh], a political counselor to the emperor that was the highest position for eunuchs of the time, and also as Shangfang Ling, where Cai oversaw the production of instruments and weapons at the Palace Workshop.

Zhang Heng (Chinese: 張衡; AD 78–139), formerly romanized Chang Heng, was a Chinese polymathic scientist and statesman who lived during the Han dynasty. Educated in the capital cities of Luoyang and Chang'an, he achieved success as an astronomer, mathematician, seismologist, hydraulic engineer, inventor, geographer, cartographer, ethnographer, artist, poet, philosopher, politician, and literary scholar.

Zhang Heng began his career as a minor civil servant in Nanyang. Eventually, he became Chief Astronomer, Prefect of the Majors for Official Carriages, and then Palace Attendant at the imperial court. His uncompromising stance on historical and calendrical issues led to his becoming a controversial figure, preventing him from rising to the status of Grand Historian. His political rivalry with the palace eunuchs during the reign of Emperor Shun (r. 125–144) led to his decision to retire from the central court to serve as an administrator of Hejian Kingdom in present-day Hebei. Zhang returned home to Nanyang for a short time, before being recalled to serve in the capital once more in 138. He died there a year later, in 139. (Full article...)

The Battle of Red Cliffs, also known as the Battle of Chibi, was a decisive naval battle in China that took place during the winter of AD 208–209. It was fought on the Yangtze River between the forces of warlords controlling different parts of the country during the end of the Han dynasty. The allied forces of Sun Quan, Liu Bei, and Liu Qi based south of the Yangtze defeated the numerically superior forces of the northern warlord Cao Cao. In so doing, Liu Bei and Sun Quan prevented Cao Cao from conquering any lands south of the Yangtze, frustrating Cao Cao's efforts to reunify the territories formerly held by the Eastern Han dynasty.

The allied victory at Red Cliffs ensured the survival of Liu Bei and Sun Quan and left them in control of the Yangtze, establishing defensible frontiers that would later serve as the basis for the states of Shu Han and Eastern Wu during the Three Kingdoms period (220–280). Historians have arrived at different conclusions in their attempts to reconstruct the timeline of events at Red Cliffs. The location of the battlefield itself remains a subject of debate: most scholars consider either a location southwest of present-day Wuhan, or a location northeast of Baqiu in present-day Yueyang, Hunan as plausible candidate sites for the battle.

"Nothing to My Name" (Chinese: 一无所有) is a 1986 Mandarin-language rock song by Cui Jian. It is widely considered Cui's most famous and most important work, and one of the most influential songs in the history of the People's Republic of China, both as a seminal point in the development of Chinese rock music and as a political sensation. The song was an unofficial anthem for Chinese youth and activists during the 1989 Tiananmen Square protests and massacre.

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.

Chinese society during the Song Dynasty (AD 960–1279) was marked by political and legal reforms, a philosophical revival of Confucianism, and the development of cities beyond administrative purposes into centers of trade, industry, and maritime commerce. The inhabitants of rural areas were mostly farmers, although some were also hunters, fishers, or government employees working in mines or the salt marshes. Conversely, shopkeepers, artisans, city guards, entertainers, laborers, and wealthy merchants lived in the county and provincial centers along with the Chinese gentry—a small, elite community of educated scholars and scholar-officials. As landholders and drafted government officials, the gentry considered themselves the leading members of society; gaining their cooperation and employment was essential for the county or provincial bureaucrat overburdened with official duties. In many ways, scholar-officials of the Song period differed from the more aristocratic scholar-officials of the Tang Dynasty (618–907). Civil service examinations became the primary means of appointment to an official post as competitors vying for official degrees dramatically increased. Frequent disagreements amongst ministers of state on ideological and policy issues led to political strife and the rise of political factions. This undermined the marriage strategies of the professional elite, which broke apart as a social group and gave way to a multitude of families that provided sons for civil service.

Confucian or Legalist scholars in ancient China—perhaps as far back as the late Zhou Dynasty (c. 1046–256 BC)—categorized all socioeconomic groups into four broad and hierarchical occupations (in descending order): the shi (scholars, or gentry), the nong (peasant farmers), the gong (artisans and craftsmen), and the shang (merchants). Wealthy landholders and officials possessed the resources to better prepare their sons for the civil service examinations, yet they were often rivaled in their power and wealth by merchants of the Song period. Merchants frequently colluded commercially and politically with officials, despite the fact that scholar-officials looked down on mercantile vocations as less respectable pursuits than farming or craftsmanship. The military also provided a means for advancement in Song society for those who became officers, even though soldiers were not highly respected members of society. Although certain domestic and familial duties were expected of women in Song society, they nonetheless enjoyed a wide range of social and legal rights in an otherwise patriarchal society. Women's improved rights to property came gradually with the increasing value of dowries offered by brides' families. (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.
