East Asian cultural sphere in the context of "A Study of History"

Self-cultivation or personal cultivation (Chinese: 修身; pinyin: xiūshēn; Wade–Giles: hsiu-shen; lit. 'cultivate oneself') is the development of one's mind or capacities through one's own efforts. Self-cultivation is the cultivation, integration, and coordination of mind and body. Although self-cultivation may be practiced and implemented as a form of cognitive therapy in psychotherapy, it goes beyond healing and self-help to also encompass self-development, self-improvement and self realisation. It is associated with attempts to go beyond and understand normal states of being, enhancing and polishing one's capacities and developing or uncovering innate human potential.

Self-cultivation also alludes to philosophical models in Mohism, Confucianism, Taoism and other Chinese philosophies, as well as in Epicureanism, and is an essential component of well-established East-Asian ethical values. Although this term applies to cultural traditions in Confucianism and Taoism, the goals and aspirations of self-cultivation in these traditions differ greatly.

Fu (Chinese: 府; pinyin: fǔ) is a traditional administrative division of Chinese origin used in the East Asian cultural sphere, translated variously as commandery, prefecture, urban prefecture, or city. They were first instituted as a regular form of administrative division of China's Tang Empire, but were later adopted in Vietnam, Japan and Korea. At present, only two fu still remain: the prefectures of Kyoto and Osaka in Japan.

The term fu is currently also used in Chinese to translate the provinces of Thailand, but not those of mainland China, Taiwan or other countries.

The Far West is a Chinese and Japanese term for Europe, or more broadly, for the entire Western world as a cultural region comparable to the East Asian cultural sphere. Originally a name for parts of Inner Asia and India, the term Far West as a Chinese exonym for the West was coined by the Italian Jesuit priest Matteo Ricci. Ricci invented the phrase as an Asian parallel to the Eurocentric notion of the Far East, which positioned Europe as a region on the fringes of a Sinocentric world. The term Far West was also used in Japan and appears in many Japanese publications.

Customs and etiquette in Chinese dining are the traditional behaviors observed while eating in Greater China. Traditional Han customs have spread throughout East Asia to varying degrees, with some regions sharing a few aspects of formal dining, which has ranged from guest seating to paying the bill.

Son of Heaven, or Tianzi (Chinese: 天子; pinyin: Tiānzǐ), was the sacred monarchial and imperial title of the Chinese sovereign. It originated with the Zhou dynasty and was founded on the political and spiritual doctrine of the Mandate of Heaven. Since the Qin dynasty, the secular imperial title of the Son of Heaven was "Huangdi".

The title, "Son of Heaven", was subsequently adopted by other Sinospheric monarchs to justify their rule. The name Celestial Empire (or "Heavenly Dynasty") was also used in reference to the status of the Chinese emperor as the Son of Heaven in the Sinosphere.

Empress dowager (also dowager empress or empress mother; Chinese and Japanese: 皇太后; pinyin: huángtàihòu; rōmaji: Kōtaigō; Korean: 황태후 (皇太后); romaja: Hwang Tae Hu; Vietnamese: Hoàng Thái Hậu (皇太后)) is the English language translation of the title given to the mother or widow of a monarch, especially in regards to Chinese, Japanese, Korean, or Vietnamese monarchs in the Chinese cultural sphere. The term however, is applied well beyond just East Asia.

The title was also given occasionally to another woman of the same generation, while a woman from the previous generation was sometimes given the title of grand empress dowager (Chinese and Japanese: 太皇太后; pinyin: tàihúangtàihòu; rōmaji: Taikōtaigō; Korean: 태황태후 (太皇太后); romaja: Tae Hwang Tae Hu; Vietnamese: Thái Hoàng Thái Hậu (太皇太后)). An empress dowager wielded power over the harem and imperial family. Numerous empress dowagers held regency during the reign of underage emperors. Many of the most prominent empress dowagers also extended their control for long periods after the emperor was old enough to govern. This was a source of political turmoil according to the traditional view of Chinese history.

Grand empress dowager (also grand dowager empress or grand empress mother) (Chinese and Japanese: 太皇太后; pinyin: tàihuángtàihòu; rōmaji: taikōtaigō; Korean: 태황태후 (太皇太后); romaja: Tae Hwang Tae Hu; Vietnamese: Thái Hoàng thái hậu (太皇太后) was a title given to the grandmother, or a woman from the same generation, of a Chinese, Japanese, Korean, or Vietnamese emperor in the Chinese cultural sphere.

Some grand empresses dowager held regency during the emperor's childhood. Some of the most prominent empress dowagers extended their regencies beyond the time when the emperor was old enough to govern alone. This was seen as a source of political turmoil, according to the traditional views of Chinese historians.

The sexagenary cycle, also known as the gānzhī (干支) or stems-and-branches, is a cycle of sixty terms used to designate successive years, historically used for recording time in China and the rest of the East Asian cultural sphere, as well as in Southeast Asia.

Each term in the sexagenary cycle consists of two Chinese characters, the first being one of the ten Heavenly Stems of the Shang-era week and the second being one of the twelve Earthly Branches representing the years of Jupiter's duodecennial orbital cycle. The first term jiǎzǐ (甲子) combines the first heavenly stem with the first earthly branch. The second term yǐchǒu (乙丑) combines the second stem with the second branch. This pattern continues until both cycles conclude simultaneously with guǐhài (癸亥), after which it begins again at jiǎzǐ. This termination at ten and twelve's least common multiple leaves half of the combinations—such as jiǎchǒu (甲丑)—unused; this is traditionally explained by reference to pairing the stems and branches according to their yin and yang properties.
