Sister Ma's aerobics video in Zhongmou can be found on a vibrating platform. "What kind of cow are you?" It's the theme song written by talented sweetheart Tang Gu for the micro film We Are All Women. The whole song mainly expresses that in this society that pays attention to equality between men and women, women have begun to have their own thoughts and judgments, and they are disdainful of men buying and selling love with money.
