The three delinquent subcultures distinguished by Cloward and Ohlin are criminal, conflict, and retreatist subcultures. Criminal subcultures provide youth with opportunities for success through criminal activities, conflict subcultures emerge in areas where legitimate and illegitimate opportunities are limited, and retreatist subcultures involve individuals who reject both legitimate and criminal means of achieving success.

It's hard to find material about Chinese subcultures -- especially because they weren't any youth subcultures until after Tiananmen Square in the late 1980's -- but here's some information on Hanfu (just one movement I could find easily) to get you started: http://en.wikipedia.org/wiki/Hanfu_movement

Some types of subcultures in sociology include countercultures, which challenge dominant cultural norms; deviant subcultures, which engage in behavior that goes against societal expectations; and identity subcultures, which form around shared identities such as race, gender, or religion. Other subcultures can be based on interests or hobbies, like music, fashion, or gaming subcultures.
