[Firehawk4]

I have this video tape of Nanyang Wing Chun wich is also called Cho Family Wing Chun or Hay Ban Opera Wing Chun , what is strange is that it seems to have Pak Mei elements there is a form called Sui Da that it has they use the Phoenix Eye Fist and Ginger Fist and there stances are somewhat similar to Pak Mei its like Wing Chun with Pak Mei Elements . Here is a list of one of the Cho Ga Wing Chun branches forms
