"Si Long" and "Fengyi" culture. "Dragon and Phoenix" stands for "male and female". Take the allusion of Ouyang Xiu, one of the eight masters in the Tang and Song Dynasties in China, as "on the donkey's back, on the bed and on the toilet". The bathroom is a good place for men to easily think about strategies and women to dress up in front of the mirror, hence the names "Si Long" and "Fengyi".
