Wu style Tai Chi is a traditional martial art. It is one of the schools of Tai Chi. It was developed and innovated mainly from the fist style of Yang style Tai Chi. Yang style Tai Chi originally had big frame and small frame. Wu style Tai Chi was gradually revised on the basis of Yang style small frame. It is known as "longevity fist, gentleman fist, medicine fist". Wu style Tai Chi is famous for its softness. The movements are relaxed and natural, continuous, and the fist styles are small and flexible. The fist frame is compact from open, but not rigid. The push-hands movements are strict and delicate, and they are quiet and not moving rashly. They are also known for their softness. It is known as "gentleman fist, medicine fist, longevity fist". Tai Chi is said to have been created by Zhang Sanfeng, a Taoist priest of Wudang. According to the Ming History "Fang Ji Zhuan", "In the 17th year of Hongwu (1368-1398), Taizu summoned Sanfeng but he refused to go. In the 25th year, he went into hiding in Yunnan. In the first year of Jianwen, Wan Puzi visited Sanfeng in Wudang, who had just returned from Pingyue, and they got along very well. In the fourth year of Yongle, the imperial scholar Hu Guang said: "Sanfeng has a deep understanding of Taoism and his boxing skills are unparalleled." This statement is generally credible. In November 2014, "Wu Style Tai Chi" was included in the extended list of representative items of the national intangible cultural heritage list (no pictures yet, welcome to provide.)
