The Chinas or Chīnaḥ (Sanskrit चीन:) are a people mentioned in ancient Indian literature from the first millennium BC, such as the Mahabharata, Laws of Manu, as well the Puranic literature. They are believed to have been Chinese.

The name Cina is commonly believed to have been derived from the Qin (Tsin or Chin) dynasty which rule in China from 221 BC. The Greco-Romans referred to China as Sina, or Sinae.

Another theory by Geoff Wade is based on a polity known as Yelang, in what is now China's Yunnan province. The inhabitants of this region referred to themselves as zina.

In the epic of the Mahabharata, the Chinas appear together with the Kiratas among the armies of king Bhagadatta of Pragjyotisa (Assam). In the Sabhaparvan, the same king is said to be surrounded the Kiratas, and the Cinas. Also in the Bhismaparvan, the army of Bhagadatta is said to consist of the Kirtas and the "yellow-colored" Cinas.

Bhishamaparva of Mahabharata also lists the Cinas with the Mlechha tribes of the north like the Yavanas, Kambojas, Kuntalas, Hunas, Parasikas, Darunas, Ramanas, Dasamalikas . These verses date to fifth century AD when the Hunas came into contact with Sassanian dynasty of Persia

Mao Zedong, also transliterated as Mao Tse-tung  listen (help·info), and commonly referred to as Chairman Mao (December 26, 1893 – September 9, 1976), was a Chinese Communist revolutionary, guerrilla warfare strategist, Marxist political philosopher, and leader of the Chinese Revolution. He was the architect and founding father of the People's Republic of China (PRC) from its establishment in 1949, and held authoritarian control over the nation until his death in 1976. His theoretical contribution to Marxism–Leninism, along with his military strategies and brand of policies, are collectively known as Maoism.

Mao rose to power by commanding the Long March, forming a Second United Front with Kuomintang (KMT) during the Second Sino-Japanese War to repel a Japanese invasion, and leading the Communist Party of China (CPC) to victory against Generalissimo Chiang Kai-shek's Kuomintang (KMT) in the Chinese Civil War. After solidifying the reunification of China through his Campaign to Suppress Counterrevolutionaries, Mao enacted sweeping land reform, by using violence and terror to overthrow the feudal landlords before seizing their large estates and dividing the land into people's communes. During the years when Mao was China’s 'Great Helmsman', a range of positive changes came to China. These included promoting the status of women, improving popular literacy, doubling the school population, providing universal housing, abolishing unemployment and inflation, increasing health care access, and dramatically raising life expectancy. In addition, China's population almost doubled during the period of Mao's leadership (from around 550 to over 900 million). As a result, Mao is still officially held in high regard by many in China as a great political strategist, military mastermind, and savior of the nation. Maoists further promote his role as a theorist, statesman, poet, and visionary, while anti-revisionists continue to defend most of his policies.
