Tongzhi
Tongzhi (Chinese:同志; pinyin:tóngzhì) is the Chinese word for "comrade" (the literal meaning of the characters is "same will" or "same purpose"). It has taken on various meanings in various contexts since the 20th century.
The term was introduced into Vernacular Chinese by Sun Yat-sen as a way of describing his followers. Following the establishment of the People's Republic of China, "tongzhi" was used to mean "comrade" in the Communist sense: it was used to address almost everyone, male and female, young and old. In recent years, however, this meaning of the term has fallen out of common usage, except within Chinese Communist Party discourse and among people of older generations.
