As a tangent from one of the recent video threads - there are several distinct Gong Baotian bagua lineages around (Gong Baozhai, Wang Zhuangfei, Wang Mingqu, Sun Ruwen, Liu Yunqiao), of which we have members of at least three of them here
Now, although there are notable differences between the various Gong style systems, some forms are similar as well.
In one of the threads, I guess someone mentioned that ligongquan (li palace fist) of Gong Baozhai's system seems to be the same form as baguatui (bagua leg) from Liu Yunqiao's system.
Another one that has been talked about is how paochui (cannon fist) of Gong Baozhai's system seems to be the same form as baoquan (leopard fist) from Fu Zhensong's system (in Hong Kong - not Gong style, but interesting nevertheless).
Any other sets that seem to be the same across systems?
Just thought it would be interesting to see what else we could find in common.
