In the VERY early days of Hong Kong Yip Man Wing Chun, two of Yip Man's students at the time were asked to demonstrate Yip Man's style of Wing Chun.

Those two men were the late Leung Sheung and Lok Yiu (who is still alive and in Hong Kong).

Here is a photo of them at that demonstration.
I know it is blurry, it is a photo of a photo.

I have a series of these that I'll put up on my website time permitting.

Perhaps someone can translate the cantonese.

Later....
