Wang seems to have the means to acquire a lot of information, such as about Alisa, Ogre's epitaph, or the Mishima Zaibatsu. He possibly left China during the start of the Mao era if not before. From the way Wang dresses and the way he speaks of jiang shi and other legends, staying in a Fujian Tulou, knowing about Mokujin in Tekken 6 and mentioning gods, he seems to hold traditions and legends in great esteem.
Wang is an old man who has seen a lot in life.
