The Wing Chun first form is called Siu Lim/Nim Tauh in some lineages and Siu Lien Tauh in others. Siu Lien means small practice/training. In the Wing Chun version I teach we use Siu Lim Tauh.
Siu means small. Lim or Nim means thought/concept. Tauh means Head. It's not the same character as the Mandarin Tao which is pronounced Do in Cantonese Together it can mean little epiphanies in the head. Some simplify is as Small thoughts or idea.
