Deletion of Leung Lan-kwai

Comment: I can't find coverage in independent reliable sources.  I found lots of "it is said" and "reportedly", but there's a lack of actual supported facts. The current sources in the article consist of a blog, an online wing chun course, and someone's diagram of the wing chun family tree.  None of those sources qualify towards meeting .  Show me some good sources and I'd be happy to reconsider
