Wang Jinrei - Knew Feng's master, as Feng asks him if he has come for revenge.
In Wang Jinrei's Tekken 6Scenario Campaign dialogues, he states that he has spoken to Lei Wulong on Feng's behalf and that he will no longer be hunted for his master's death. Feng's master is not mentioned after this game and neither do the police seem to be hunting Feng any more, so it is likely that this interaction is canon.
Feng Wei trains before his master.
