Looking at Shifu Han's 10 section Tan tui confirms in my mind that the 10 section and 12 section version are connected. In some sections (ie. 1, 3, 4) the similarities are more apparent than others. Section 8 and 9 however are quite different. Despite these difference the similarities in the underlining patterns can be seen. This in my mind confirms the traditional history of Shaolin Tan tui. We went thought through this in another early discussion at some length. Basically tradition according to the older generation says that Shaolin monks adopted tan tui making some changes to it and added two sections. From what I understand Shanghai Jingwu propagated the same history of it as we do.
Our Tan Tui comes from different linage than the one that came from Chao Lien-ho and the Shanghai Jingwu. Our lineage moved from the Luoyang area in Henan province to Beijing during the mid 1800's then to Shanghai during the 1910's.
At lest in looking at Chan Kin Man's book "Northern Shaolin Twelve Tantui Boxing Series" published by the Hong Kong Chan Hong Heung Kung Fu Association in 1984, I would say that our tan tui is very simular although not identical to the Jingwu version.
However many of the applications are different, at lest as shown in the above mentioned book.
e.g. Section 11, which shows a catch-trap-throw, we do this also but quite differently. Our application for section 4 is different.
