Tai Ji Chuan in China is soft and restrained, which is a kind of martial arts that integrates health and defense. It uses the principle of harmony between Yin and Yang of Taoism and uses ideas to penetrate the whole body to achieve the effect of self-cultivation and longevity. It is a popular sport.
But there are some differences about the origin of Tai Ji Chuan. Before War of Resistance against Japanese Aggression, it was generally acknowledged that Zhang Sanfeng, the founder of wu-tang clan, was the founder of Tai Ji Chuan. Zhang Sanfeng's martial arts, such as Tai Ji Chuan, Bagua Boxing, Xingyiquan, five elements boxing, Mixed Yuan Boxing and Xuanwu Stick, are all based on the principles of Taoism.
Tai Ji Chuan's emphasis on the coordination and unity of meaning, qi and strength is also in line with Taoism's proposition of conforming to nature and being indifferent to inaction. Besides, Wudang Kung Fu is famous all over the world, so no one has questioned the origin of Tai Ji Chuan before.
However, when people later studied the origin of Tai Ji Chuan, they found that the Tai Ji Chuan created by Chen Wangting was earlier than that created by Zhang Sanfeng, and according to the records of Tai Ji Chuan moves left by the Chen family, it was almost the same as that left by Wudang Tai Ji Chuan.
