In many of the Yip Man photos, and those of his martial descendents, we see the couplet (dui lian):
Wing Chun chuen tsing tung
Waa Haa tsun hung fung
My question is: "What does it mean?"
The first line I understand to be: "transmit the orthodox Wing Chun". I would take this to be that teachers should be true to their teaching and try and transmit the true spirit of Wing Chun.
The next line I haven't got a clue. "Waa" traditional refers to all things Chinese; for example "waa yun" means "Chinese person". But what is "Waa Haa"?
"Tsun Hung Fung" seems to imply doing "heroic" deeds and "shaking the earth". A bit ambitious, but I would guess this means to promote "the glory of Wing Chun" .... using your fists I presume rather than your mouth.
