All writings about Zhang Sanfeng before the mid-Qing Dynasty have nothing to do with martial arts and Tai Chi. Why did Zhang Sanfeng become the ancestor of Neijiaquan?

It’s nothing more than fame and wealth.

Taijiquan first originated from the Chen family (the name was artificially distinguished by later generations), and later derived from Yang, Wu, Wu, Sun, He (Zhao Bao) and so on. Huleijia belongs to Zhaobao.

Others, some are not familiar to the public due to their small spread, and some are "created" by current people.
