Many of the moves in Fan tzi forms are very similar in function and looks to moves in Xin Yi Quan, such as stepping out with one foot raised slightly above the ground.
Also, Yue family martial art style, which is recognized as a root to Dai family Xin Yi and Henan Xin Yi styles, is atributed to come from Yue Fei’s teacher, who was Zhou Dong, who taught/practiced Shaolin (Lohan) and FanTzi (when it was called Ba Shan Fan).
he Fanzi Quan ballad says: “Wu Mu has passed down the Fanzi Quan which has mystery in its straightforward movements.” Wu Mu is the other name for Yue Fei.
And, “dantien rotations and power releasing methods, which at times have a close similarity to the xinyiliuhe methods” is what is attributed to Fantzi.
What is very interesting about this statementis that eventually what is called Yueh Fei Jia Quan reached Henan province, via the decendents of one of Yueh Fei’s army officers, Niu Gao, and eventually Dai Long Beng and his sons, and Guo Waihen, went to Shijiadian in Henan where dai owned an inn in 1838, learned this Yueh Fei Jia Quan from Niu Xixian in 1841,
and he incoporated the “dantien rotations and power releasing methods, which at times have a close similarity to the xinyiliuhe methods” into his Xin Yi Liu He Quan.
