Ruan Qi, whose net name is "Devil Consultant", graduated from Peking University, majoring in psychology. For decades, I have been devoted to the study of men's and women's communication, including street chat and subsequent communication. At the end of 2007, I began to record my chat experience for more than ten years in Douban's "Chat Group", which was sought after by otaku and otaku. Later, I set up a "devil chat training class" to lead students to start the ability training of hitting on strangers on the streets of Beijing and help thousands of men successfully find their favorite object. Known as the "godfather".
