The Sinosphere, also known as the Chinese cultural sphere, East Asian cultural sphere, or the Sinic world, encompasses multiple countries in East Asia and Southeast Asia that were historically heavily influenced by Chinese culture. The Sinosphere comprises Greater China, Japan, Korea, Vietnam and historically the Ryukyuans. Other definitions may include the regions of modern-day Mongolia and Singapore, due either to historical Chinese influence or a contemporary overseas Chinese population. The Sinosphere is different from the Sinophone world, which indicates regions where the Chinese language is spoken.

Imperial China was a major regional power in Eastern Asia and exerted influence on tributary states and neighboring states, including Japan, Korea, and Vietnam. These interactions brought ideological and cultural influences rooted in Confucianism, Buddhism, and Taoism. The four cultures were ruled by their respective emperors under similar imperial systems, furthermore, the adoption of the Confucian-based imperial examination system deeply influenced the bureaucracy and social structure of Korea and Vietnam. Chinese inventions influenced, and were in turn influenced by, innovations of the other cultures in governance, philosophy, science, and the arts. Literary Chinese became the written lingua franca for bureaucracy and communications, and Chinese characters became locally adapted as kanji in Japan, hanja in Korea, and chữ Hán in Vietnam.

The Han dynasty (202 BC – 220 AD) was the second imperial dynasty of China, following the Qin dynasty (221–207 BC). It was divided into the periods of Western (Former) Han (202 BC – 9 AD) and Eastern (Later) Han (25–220 AD), briefly interrupted by the Xin dynasty (9–23 AD) of Wang Mang. The capital of Western Han was Chang'an, and the capital of Eastern Han was Luoyang. The emperor headed the government, promulgating all written laws, serving as commander-in-chief of the armed forces, and presiding as the chief executive official. He appointed all government officials who earned a salary of 600 bushels of grain or more (though these salaries were largely paid in coin cash) with the help of advisors who reviewed each nominee. The empress dowager could either be the emperor's actual or symbolic mother, and was in practice more respected than the emperor, as she could override his decisions; she could even make decisions on behalf of the emperor in dilemma matters of the country or for the order and continuation of the dynasty. If necessary, with the support of the courtiers, she would decide on his successor or his dismissal, although such a challenge was only raised by the empress dowager to the emperor during the emperor's youth or incapacity. The emperor's executive powers could also be practiced by any official upon whom he bestowed the Staff of Authority. These powers included the right to execute criminals without the imperial court's permission.

Near the beginning of the dynasty, semi-autonomous regional kings rivaled the emperor's authority. This autonomy was greatly diminished when the imperial court enacted reforms following the threats to central control like the Rebellion of the Seven States. The end of the Han dynasty came about during a time of civil, military and religious upheaval, which resulted in the period of Three Kingdoms.

A dragon is a magical legendary creature that appears in the folklore of multiple cultures worldwide. Beliefs about dragons vary considerably through regions, but dragons in Western cultures since the High Middle Ages have often been depicted as winged, horned, and capable of breathing fire. Dragons in Eastern cultures are usually depicted as wingless, four-legged, serpentine creatures with above-average intelligence. Commonalities between dragons' traits are often a hybridization of reptilian, mammalian, and avian features.

A national flag is a flag that represents and symbolizes a given nation. It is flown by the government of that nation, but can also be flown by its citizens. A national flag is typically designed with specific meanings for its colors and symbols, which may also be used separately from the flag as a symbol of the nation. The design of a national flag is sometimes altered after the occurrence of important historical events.

Fenghuang (/fʌŋˈwɑːŋ/ fung-HWAHNG) are mythological birds featuring in traditions throughout the Sinosphere. Fenghuang are understood to reign over all other birds: males and females were originally termed feng and huang respectively, but a gender distinction is typically no longer made, and fenghuang are generally considered a feminine entity to be paired with the traditionally masculine Chinese dragon.

In the West, they are commonly called Chinese phoenixes, although mythological similarities with the Western/Persian phoenix are superficial.

Bixi, or Bi Xi (Wade–Giles: Pi-hsi), is a figure from Chinese mythology. One of the nine sons of the Dragon King, he is depicted as a dragon with the shell of a turtle. Stone sculptures of Bixi have been used in Chinese culture for centuries as a decorative plinth for commemorative steles and tablets, particularly in the funerary complexes of its later emperors and to commemorate important events, such as an imperial visit or the anniversary of a World War II victory. They are also used at the bases of bridges and archways. Sculptures of Bixi are traditionally rubbed for good luck, which can cause conservation issues. They can be found throughout East Asia and the Russian Far East.

Chiwen (Chinese: 蚩吻; pinyin: chīwěn; Wade–Giles: ch'ih-wen; lit. 'hornless-dragon mouth') is a roof ornamental motif in traditional Chinese architecture and art. Chiwen is also the name of a Chinese dragon that mixes features of a fish, and in Chinese mythology is one of the nine sons of the dragon, which are also used as imperial roof decorations.As architectural ornaments or waterspouts, they are comparable with Western gargoyles, but are not related to the mythological character.

The Dragon King, also known as the Dragon God, is a celestial creature, water and weather god in Asian mythology. They can be found in various cultural and religious symbolic materials all around Asia, specifically in South, Southeast Asia and distinctly in East Asian cultures (Chinese folk-religion). He is known in many different names across Asia depending on the local language such as, Ryūō in Japanese. (Korean Dragon, Indian Dragon, Vietnamese Dragon and more)

He can manipulate and control the weather, move seasons and bring rainfall with his divine power at his own will, thus, he is regarded as the dispenser of rain, divine ruler of the Seas, rivers and water bodies, commanding over all bodies of water. He is the collective personification of the ancient concept of the lóng in Chinese culture and Nāgarāja in Indian culture. It is described that they have their own under-water palace and a royal court system of their own.

The Azure Dragon (Chinese: 青龍; pinyin: Qīnglóng) is one of the Dragon Gods who represent the mount or chthonic forces of the Five Regions' Highest Deities (五方上帝; Wǔfāng Shàngdì). It is also one of the Four Symbols of the Chinese constellations, which are the astral representations of the Wufang Shangdi. The Azure Dragon represents the east and the spring season. It is also sometimes referred to as the Blue-green Dragon, Green Dragon, or the Blue Dragon (蒼龍; Cānglóng).

The Dragon is frequently referred to in the media, feng shui, other cultures, and in various venues as the Green Dragon and the Avalon Dragon. His cardinal direction's epithet is "Bluegreen Dragon of the East" (東方青龍; Dōngfāng Qīnglóng or 東方蒼龍; Dōngfāng Cānglóng).

The Yellow Dragon (simplified Chinese: 黄龙; traditional Chinese: 黃龍; pinyin: Huánglóng; Cantonese Yale: Wong4 Lung4) is the zoomorphic incarnation of the Yellow Emperor of the center of the universe in Chinese religion and mythology.

The Yellow Emperor or Yellow Deity was conceived by Fubao, who became pregnant after seeing a yellow ray of light turning around the Northern Dipper (in Chinese theology the principal symbol of God). Twenty-four months later, the Yellow Emperor was born and was associated with the color yellow because it is the color of the earth (地; Dì), the material substance in which he incarnated.

The Harbin cranium is a nearly complete skull of an archaic human found in sediments of the Songhua River near Harbin on the Northeast China Plain, dating to at minimum 146,000 years ago during the Middle Pleistocene. It was described in 2021, and that year it was assigned as the holotype of the new human species Homo longi ("dragon man") named after Long Jiang, where the fossil skull was discovered . The Harbin cranium was initially hypothesized to belong to the same species as the Denisovans, and subsequent proteomics and mitochondrial DNA analyses confirmed its Denisovan affinities.

The Harbin cranium is broadly anatomically similar to other Middle Pleistocene Chinese specimens. Like other archaic humans, the skull is low and long, with massively developed brow ridges, wide eye sockets, and a large mouth. The skull is the longest ever found from any human species. Like modern humans and the much earlier Homo antecessor, the face is rather flat, but with a larger nose. The brain volume was 1,420 cc, within the range of modern humans and Neanderthals.

Shenlong (simplified Chinese: 神龙; traditional Chinese: 神龍; pinyin: shén lóng; lit. 'divine dragon') is a Chinese reusable robotic spaceplane currently in development. Only a few pictures have appeared since it was revealed in late 2007.

Nine Dragons (九龍圖卷; Jiǔlóngtú juǎn) is a handscroll painting by Chinese artist Chen Rong. Painted in 1244, it depicts the apparitions of dragons soaring amidst clouds, mists, whirlpools, rocky mountains and fire, the painting refers to the dynamic forces of nature in Daoism and the liquid, water-like essence of the Tao. The depicted dragons are associated with nine sons of the Dragon King, while the number nine itself is considered auspicious in Chinese astrology and folk beliefs.

Areas of the painting are spattered with drops of ink, either flung or blown onto the surface in a manner similar to action painting. This is a conscious evocation of rain and may even be a rainmaking ritual by the artist; lines 32 and 33 of Chen Rong's poetic inscription describe how his dragons either could, or did, produce rainfall:

A guandao is a type of Chinese polearm that is used in some forms of Chinese martial arts. In Chinese, it is properly called a yanyuedao (偃月刀; lit. "reclining moon blade"), the name under which it appears in texts such as the Wujing Zongyao and Huangchao Liqi Tushi. It consists of a heavy blade with a spike at the back and sometimes also a notch at the spike's upper base that can catch an opponent's weapon. In addition, there are often irregular serrations that lead the back edge of the blade to the spike. The blade is mounted atop a 1.5 to 1.8 m (4 ft 11 in to 5 ft 11 in) long wooden or metal pole and a pointed metal counterweight on the opposite end, which is used to balance the heavy blade and for striking.

On modern versions, a red sash or tassel is attached at the joint of the pole and blade. Variations include rings along the length of the straight back edge as found in the nine-ring guandao, the tip curling into a rounded spiral as in the elephant guandao, or a more ornate design as exemplified by the dragon head guandao. However, apart from the "elephant guandao", none of these variations seem to have historical grounding.

The economic history of China covers thousands of years and the region has undergone alternating cycles of prosperity and decline. China, for the last two millennia, was one of the world's largest and most advanced economies. Economic historians usually divide China's history into three periods: the pre-imperial era before the rise of the Qin; the early imperial era from the Qin to the rise of the Song (221 BCE to 960 CE); and the late imperial era, from the Song to the fall of the Qing.

Neolithic agriculture had developed in China by roughly 8,000 BCE. Stratified Bronze Age cultures, such as Erlitou, emerged by the third millennium BCE. Under the Shang (16th–11th centuries BCE) and Western Zhou (11th–8th centuries BCE), a dependent labor force worked in large-scale foundries and workshops to produce bronzes and silk for the elite. The agricultural surpluses produced by the manorial economy supported these early handicraft industries as well as urban centers and considerable armies. This system began to disintegrate after the collapse of the Western Zhou in 771 BCE, leaving China fragmented during the Spring and Autumn (8th–5th centuries BCE) and Warring States eras (5th–3rd centuries BCE).
