How long it take you to learn all of wing chun's forms?

Just curious Andrew, are those dummy sets after instructor level, are they the one’s Victor was talking about that Cheung changed after that demo he did in 82’ for all of his seniors to see? Appartently the set was too hard for most to pick up so he changed it. What are the differences between these sets and the public version?

I’m not familiar with the reference you are discussing.

The sets I am talking about are not alterations to the “public” sets, whatever that means, but additional sets.

Most I think would have seen the oft-taught “additional” set which is largely tseun sao based.

Of the others, I do not have the authority to discuss details. Some are just mixing of different elements from other sets, of those that are not, they involve (by set)

kicking (in addition to the 10th/11th sets)
chi gerk
garn/tsuen

if this rings a bell, you know what I’m talking about. If not, I’m not at liberty to discuss further at my Sifu’s request, even with my sidais below level 10.
