Comrades refer to like-minded people. In ancient China, comrades, like gentlemen, elders and gentlemen, were all appellations among friends. In the Spring and Autumn Period, Zuo Qiuming explained the word "comrade" in "Mandarin in this Four Years": "One heart and one mind is a comrade." Liu Tao Chuan in the Later Han Dynasty said, "Making friends must be gay."

In China, comrades are also widely used as greetings between strangers. Comrade is a friendly address to classmates, which embodies a kind of respect for people and has a cordial connotation.
