Zhang Houwu (Yiquan) in Shenzhen

[nicklinjm]

Came across some videos of a Dachengquan / Yiquan teacher in Shenzhen called Zhang Houwu, apparently a long-term disciple of Wang Binkui. His ability to 'launch' people and get out of seemingly very disadvantageous mechanical situations (e.g. arm locked up behind his back) seems completely out of proportion to his size / strength:





Has anyone heard of or met this teacher? Any thoughts from people that actually do Yiquan / Dachengquan?
