Greater China in the context of "Han Chinese"

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 Chinese people, or simply Chinese, are people or ethnic groups identified with China, usually through ethnicity, nationality, citizenship, social construct or other affiliation.

Chinese people are known as Zhongguoren (simplified Chinese: 中国人; traditional Chinese: 中國人) or as Huaren (simplified Chinese: 华人; traditional Chinese: 華人) by speakers of standard Chinese, including those living in Greater China as well as overseas Chinese. Although both terms both refer to Chinese people, their usage depends on the person and context. The former term is commonly (but not exclusively) used to refer to the citizens of the People's Republic of China—especially mainland China. The term Huaren is used to refer to ethnic Chinese, and is more often used for those who reside overseas or are non-citizens of China.

Overseas Chinese people or the Chinese diaspora are a diaspora people of Chinese origin who reside outside Greater China (mainland China, Hong Kong, Macau, and Taiwan). As of 2011, there were over 40.3 million overseas Chinese. As of 2023, there were 10.5 million people living outside mainland China who were born in mainland China, corresponding to 0.7 percent of China's population. Overall, China has a low percent of its population living overseas.

Sinophone, which means "Chinese-speaking", typically refers to an individual who speaks at least one variety of Chinese (that is, one of the Sinitic languages). Academic writers often use the term Sinophone in two definitions: either specifically "Chinese-speaking populations where it is a minority language, excluding mainland China, Hong Kong, Macau, and Taiwan" or generally "Chinese-speaking areas, including where it is an official language". Many authors use the collocation Sinophone world or Chinese-speaking world to mean the Chinese-speaking world itself (consisting of Greater China and Singapore) or the distribution of the Chinese diaspora outside of Greater China.

Mandarin Chinese is the most commonly spoken variety of the Chinese languages today, with over 1 billion total speakers (approximately 12% of the world population), of which about 900 million are native speakers, making it the most spoken first language in the world and second most spoken overall. It is the official variety of Chinese in mainland China, Taiwan, and Singapore. Meanwhile, Cantonese is the official variety of Chinese in Hong Kong and Macau and is also widely spoken among significant overseas Chinese communities in Southeast Asia as well as the rest of the world.

Chinese martial arts, commonly referred to with umbrella terms kung fu (/ˈkʌŋ ˈfuː/; Chinese: 功夫; pinyin: gōngfu; Jyutping: gung1 fu1; Cantonese Yale: gūng fū), kuoshu (Chinese: 國術; pinyin: guóshù; Jyutping: gwok3 seot6) or wushu (Chinese: 武術; pinyin: wǔshù; Jyutping: mou5 seot6), are multiple fighting styles that have developed over the centuries in Greater China. These fighting styles are often classified according to common traits, identified as "families" of martial arts. Examples of such traits include Shaolinquan (少林拳) physical exercises involving Five Animals (五形) mimicry or training methods inspired by Old Chinese philosophies, religions and legends. Styles that focus on qi manipulation are called internal (内家拳; nèijiāquán), while others that concentrate on improving muscle and cardiovascular fitness are called external (外家拳; wàijiāquán). Geographical associations, as in northern (北拳; běiquán) and southern (南拳; nánquán), is another popular classification method.
