Published work generally deals with women as visible participants in revolution, employment as vehicles for women's liberation, Confucianism and the cultural concept of family as sources of women's oppression.

This reflects the decline of the extended family and the growth in women's agency in the marriage transaction.[29] In recent scholarship in China, the concept of gender has yielded a bounty of new knowledge in English- and Chinese-language writings.[30][31]
