In the fight : Yi Long vs Buakaw on 6 Jun 2015, Yi Long had held Buakaw`s kicking leg thrice (once in round 1 and twice in round 3 ) under his arm-pit.  If Yi Long used tai-ji movement, namely 海底针 as shown in my video, Buakaw`s leg would be fractured ! Actually Yi Long had 2 martial art consultants around him, namely Zhu and Zhao. They should remind Yi Long to use 海底针 after the 1st round. Otherwise Yi Long would not miss 2 more chances to disable Buakaw`s leg in the 3rd round. It is an unforgiving mistake !
