Wing Chun's First Form Yip Man Sil Lim TauSil Lim Tau, sometimes referred to as Siu Nim Tao, is the first of the hand forms of Wing Chun Kung Fu. It teaches the student the basics of the martial art. The form has been adapted and changed over the last few hundred years, but it is thought that the form was inspired by movements from both crane style kung fu and snake style kung fu. The form has evolved differently as styles of Wing Chun diverged. The snake element can be seen more in Yuen Kay San
