Prior to learning from Cao Jiwu, Dai Long Bang was already a master in Taijiquan.
[2] Dai Longbang further developed Xinyi and wrote the book “The Six Harmonies Fists”, which constitutes the written classics of the style.
However, Dai Long Bang himself states in his book that he did not create Xinyi Quan.
The Dai brothers were in the vegetable wholesale business, and did not publicly teach to others outside their family.
However, after many years of keeping the art within the family, Dai Long Bang's son Dai Wenxiong accepted Li Luoneng as a student, who went on to become a very famous martial artist, and a popularizer of the art.
