去毛 (qù máo): hair removal

While most search results for the term “去毛” are for sites selling creams and razors, the term also has a political meaning. Mao Zedong’s surname literally means “hair;” therefore, to “de-hair” can also mean to de-Mao; “去毛化” means de-Mao-ification. De-Mao-ification refers to the minimization of Mao Zedong thought and Mao’s role in history.
