Simplified Chinese characters in the context of "Tongchuan"

The East China Sea is a marginal sea of the Western Pacific Ocean, located directly offshore from East China. China names the body of water along its eastern coast as "East Sea" (Dōng Hǎi, simplified Chinese: 东海; traditional Chinese: 東海) due to direction, the name of "East China Sea" is otherwise designated as a formal name by International Hydrographic Organization (IHO) and used internationally.

It covers an area of roughly 1,249,000 square kilometers (482,000 sq mi). The sea's northern extension between Korean Peninsula and mainland China is the Yellow Sea, separated by an imaginary line between the southwestern tip of South Korea's Jeju Island and the eastern tip of Qidong at the Yangtze River estuary.

Sima Tan (traditional Chinese: 司馬談; simplified Chinese: 司马谈; pinyin: Sīmǎ Tán; Wade–Giles: Ssu-ma T'an; c. 165–110 BCE) was a Chinese astrologist, astronomer, and historian during the Western Han dynasty. His work Records of the Grand Historian was completed by his son Sima Qian, who is considered the founder of Chinese historiography.

The Shiji (simplified Chinese: 史记; traditional Chinese: 史記; pinyin: Shǐjì; lit. 'Historical Records'), also known as Records of the Grand Historian or The Grand Scribe's Records (simplified Chinese: 太史公书; traditional Chinese: 太史公書; pinyin: Tàishǐgōng shū), is a Chinese historical text that is the first of the Twenty-Four Histories of imperial China. It was written during the late 2nd and early 1st centuries BC by the Han dynasty historian Sima Qian, building upon work begun by his father Sima Tan. The work covers a 2,500-year period from the age of the legendary Yellow Emperor to the reign of Emperor Wu of Han in the author's own time, and describes the world as it was known to the Chinese of the Western Han dynasty.

The Shiji has been called a "foundational text in Chinese civilization". Following Confucius and Qin Shi Huang, "Sima Qian was one of the creators of Imperial China; by providing definitive biographies, he effectively shaped the enduring images of these two earlier figures." The Shiji set the model for all subsequent dynastic histories of China. In contrast to Western historiographical conventions, the Shiji does not treat history as "a continuous, sweeping narrative", but rather breaks it up into smaller, overlapping units dealing with famous leaders, individuals, and major topics of significance.

Chinese philosophy (simplified Chinese: 中国哲学; traditional Chinese: 中國哲學) refers to the philosophical traditions that originated and developed within the historical and cultural context of China. It encompasses systematic reflections on issues such as existence, knowledge, ethics, and politics. Evolving over more than two millennia, Chinese philosophy includes classical traditions such as Confucianism, Daoism, and Buddhism, as well as modern responses to Western philosophical currents. As a cultural form of philosophy, it addresses universal philosophical concerns while also reflecting the specific historical and social conditions of China.

The historical development of Chinese philosophy began during the Spring and Autumn and Warring States periods, a time known as the "Hundred Schools of Thought". Major schools such as Confucianism, Daoism, Mohism, and Legalism emerged with distinct views on human nature, social order, and political authority. During the Han dynasty, Confucianism was established as the official ideology, shaping China's intellectual and political systems for centuries. In subsequent eras, Chinese philosophy integrated influences from Indian Buddhism, giving rise to new developments such as Neo-Confucianism in the Song and Ming dynasties. In the modern period, Chinese thinkers engaged with Western thought, resulting in the emergence of Three Principles of the People, Chinese Marxism, New Confucianism, and other philosophical movements. Throughout the 20th century, these traditions were reshaped by political upheaval and continue to evolve today.

The Yangtze River, Yangzi River (English: /ˈjæŋtsi/ or /ˈjɑːŋtsi/) or Chang Jiang (simplified Chinese: 长江; traditional Chinese: 長江; pinyin: Cháng Jiāng; lit. 'long river') is the longest river in China and the third-longest river in the world. It rises at Jari Hill in the Tanggula Mountains of the Tibetan Plateau and flows, 6,374 km (3,961 mi) including the Dam Qu River, the longest source of the Yangtze, in a generally easterly direction to the East China Sea. It is the fifth-largest primary river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country's population.

The Yangtze has played a major role in the history, culture, and economy of China. For thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking, and war. The Yangtze Delta generates as much as 20% of China's GDP, and the Three Gorges Dam on the Yangtze is the largest hydro-electric power station in the world. In mid-2014, the Chinese government announced it was building a multi-tier transport network, comprising railways, roads and airports to create a new economic belt alongside the river.

Yangtze civilization (simplified Chinese: 长江文明; traditional Chinese: 長江文明) is a generic name for various ancient Neolithic and Bronze Age cultures from the Yangtze basin in China, a contemporary civilization by the neighboring Yellow River civilization.

Chinese culture (simplified Chinese: 中华文化; traditional Chinese: 中華文化; pinyin: Zhōnghuá wénhuà) is one of the world's earliest cultures, said to originate five thousand years ago. The culture prevails across a large geographical region in East Asia called the Sinosphere as a whole and is extremely diverse, with customs and traditions varying greatly between regions. The terms 'China' and the geographical landmass of 'China' have shifted across the centuries, before the name 'China' became commonplace. Chinese civilization is historically considered a dominant culture of East Asia. Chinese culture exerted profound influence on the philosophy, customs, politics, and traditions of Asia. Chinese characters, ceramics, architecture, music, dance, literature, martial arts, cuisine, arts, philosophy, etiquette, religion, politics, and history have had global influence, while its traditions and festivals are celebrated, instilled, and practiced by people around the world.

Fajia (Chinese: 法家; pinyin: fǎjiā), or the School of fa (incl. law, method), often translated Legalism, was a bibliographic school of primarily Warring States period classical Chinese philosophy, including more administrative works traditionally said to be rooted in Huang-Lao Daoism. Addressing practical governance challenges of the unstable feudal system, their ideas 'contributed greatly to the formation of the Chinese empire' and bureaucracy, advocating concepts including rule by law, sophisticated administrative technique, and ideas of state and sovereign power. They are often interpreted along realist lines. Though persisting, the Qin to Tang were more characterized by the 'centralizing tendencies' of their traditions.

The school incorporates the more legalistic ideas of Li Kui and Shang Yang, and more administrative Shen Buhai and Shen Dao, with Shen Buhai, Shen Dao, and Han Fei traditionally said by Sima Qian to be rooted in Huang-Lao (Daoism). Shen Dao may have been a significant early influence for Daoism and administration. These earlier currents were synthesized in the Han Feizi, including some of the earliest commentaries on the Daoist text Daodejing. The later Han dynasty considered Guan Zhong to be a forefather of the school, with the Guanzi added later. Later dynasties regarded Xun Kuang as a teacher of Han Fei and Qin Chancellor Li Si, as attested by Sima Qian, approvingly included during the 1970s along with figures like Zhang Binglin.

East China (Chinese: 华东; pinyin: huá dōng) is a geographical region in the People's Republic of China, mainly consisting of seven province-level administrative divisions, namely the provinces (from north to south) Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, and the direct-administered municipality Shanghai.

The region was defined in 1945 as the jurisdiction area of the Central Committee's East China Bureau (华东局), which was a merger politburo agency of the Shandong Bureau and the Central China Bureau previously established during the Second Sino-Japanese War. After the founding of the People's Republic of China, the region included all the aforementioned provinces except Jiangxi, which was previously considered part of South Central China before being reassigned in 1961. The East China Bureau was abolished in 1966 due to the Cultural Revolution, but in 1970 the fourth five-year plan redefined the region as the East China Coordinated Region (华东协作区), which supported the logistics of the Jinan and Nanjing Military Regions. This geographical definition was retained after the economic reform of the 1980s.
