This statement is incorrect, the ancient Luo Cheng, Qin Qiong, Wu Sung, Yan Qing, Lu Bu, Zhao Yun, Lan Ling Wang, Yue Fei, Yang Liu Lang are traditional martial arts masters, all have a fit body looks, modern Ji Interco, Li Cunyi, Sun Lutang, Xue Beng, Zhu Guolu, Han Mu Man, etc. are fit body, and the contemporary Bruce Lee, Lijiang fast knife, etc. have a proud body, who said that the traditional martial arts folk masters body are generally unattractive? This is unfounded
