The history of Chinese literature extends thousands of years, from the earliest recorded dynastic court archives to the mature vernacular fiction novels that arose during the Ming dynasty to entertain the masses of literate Chinese. The introduction of widespread woodblock printing during the Tang dynasty (618–907) and the invention of movable type printing by Bi Sheng (990–1051) during the Song dynasty (960–1279) rapidly spread written knowledge throughout China. In more modern times, the author Lu Xun (1881–1936) is considered an influential voice of baihua literature in China.
This is a wide-ranging alphabetical list of philosophers from the Eastern traditions of philosophy, with special interest in Indo-Chinese philosophy. The list stops at the year 1950, after which philosophers fall into the category of contemporary philosophy.

The Presidential Early Career Award for Scientists and Engineers (PECASE) is the highest honor bestowed by the United States government on outstanding scientists and engineers in the early stages of their independent research careers. The White House, following recommendations from participating agencies, confers the awards annually. To be eligible for a Presidential Award, an individual must be a US citizen, national or permanent resident. Some of the winning scientists and engineers receive up to a five-year research grant.

A eunuch is a castrated man. Castration has had a social function in history. In China, castration included the removal of the penis and the testicles (emasculation). A knife removed both organs at the same time. Eunuchs have existed in China since about 146 AD, during the reign of Emperor Huan of Han and were common as civil servants by the Qin dynasty. From ancient times to the Sui dynasty, castration was a traditional punishment and a means of gaining employment in the imperial service. Some eunuchs, such as the Ming dynasty official Zheng He, gained power that superseded that of the Grand Secretaries. Self-castration was not uncommon, although it was not always performed thoroughly and was later banned.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2018.
A number of significant scientific events occurred in 2020.

The COVID-19 pandemic was first reported in the city of Wuhan, Hubei, China, in December 2019. The origins of the virus have subsequently led to an increase in acts and displays of Sinophobia, as well as prejudice, xenophobia, discrimination, violence, and racism against people of East Asian and Southeast Asian descent and appearance around the world. With the spread of the pandemic and formation of hotspots, such as those in Asia, Europe, and the Americas, discrimination against people from these hotspots has been reported.
A microswimmer is a microscopic object with the ability to move in a fluid environment. Natural microswimmers are found everywhere in the natural world as biological microorganisms, such as bacteria, archaea, protists, sperm and microanimals. Since the turn of the millennium there has been increasing interest in manufacturing synthetic and biohybrid microswimmers. Although only two decades have passed since their emergence, they have already shown promise for various biomedical and environmental applications.
