TWC GM William Cheung's Lineage - Ving Tsun Museum Claim

[Tong Chuang]

I noticed on the Ving Tsun Museum Family Tree it seems to be implying that GM William Cheung learnt Hung Fa Yi from 'GM Hakka Keung's students in Hong Kong' in the 1970's period.



see

Can anybody corroborate this claim?

I understood that he had already left for Australia by this time.

Apart from this post
http://www.kungfumagazine.com/forum/...ht=HAKKA+KEUNG
there is no other information about GM Hakka Keung, who was apparently a Hung Suen / Hung Fa Yi Grandmaster, one of only 4 disciples of GM Wang Ming

If true, this link might explain why TWC and Hung Fa Yi have many similarities but would undermine the Leung Bik / Yip Man / William Cheung teaching claim.
