If it is exercise, it is Yang. Chen taijichuan kept some vigorous kung fu in active fighting, such as shaking his feet. Tai Ji Chuan, which is popular in the world, evolved from Chen Tai Ji Chuan, but it was Tai Ji Chuan who really spread it to the world. Tai Ji Chuan's origin, Chen Tai Ji Chuan, is rated by many Tai Ji Chuan learners as Tai Ji Chuan, which is least like Tai Ji Chuan, because of its strong movements. Yang Tai's Biography is different from Chen Shi's because Shi Yang removed those moves that were strong but not easy to practice and hurt his health in order to teach Manchu aristocratic boxing. This greatly catered to the preferences of the nobles, who advertised. Of course, due to Yang's teaching, Tai Ji Chuan has developed from a minority boxing to a big boxing. But because of this, Tai Ji Chuan has gradually turned into gymnastics instead of fighting martial arts.
