The last Chinese assassins society was called "蓝衣社 (Lan Yi She) - blue shirt club", it was leaded by "戴笠 Dai Li". During WWII, Dai had sent many assassins to those Chinese military generals. Those assassin's mission was to collect evidence. If any Chinese military general was found to contact with the communist party, the assassin would kill that military general right way. When Dai gave order to his assassins, Dai would give them a hand gun and said, "Complete the mission, or kill yourself." The one walked next to Chiang Kai-shek (The Chinese president back then) was Dai Li.
Buy no means an expert on nerve strikes but from what i have seen both Chinese and Japanese strikes rely on the same points, originating in Indianan Buddhist medicine and codified as acupressure meridians and points.
