Deletion of Lok Yiu

Comment: The only mentions I can find of him are as one of Ip Man's early students.  That's the passing mention in the history of Wing Chun book.  The article's other source is a mention of his death in the "Wing Chun Teahouse", self described as "a community-contributed online magazine of wing chun" (which would seem to indicate it can't be considered an independent reliable source).  Even that obituary says his notability is because he was an early student of Ip Man, but  applies.  The other mentions my search found all seem to be from schools claiming lineage from him, which means none of them can be considered independent.  I understand that his time and location don't lend themselves to an English internet search, but that's all I can do
