Anyone know tang lang chuan?

Tang Lang Chuan, if directly translate from mandarine, is `praying mantis fist' (I hope this is right). I've just gone to the extra curricular class, which is tang lang chuan. It's fun, for i've never done anything like this before. But i don't think i can learn a lot in 14 weeks of classes. The teacher is quite long winded, he talks a lot, haha. But then, one can still see he's very active and energetic. I hope i can belike that when i'm old, that's why i need to exercise a lot. Think i really need to have a more disclipline life style, so that i won't be eating like mad every time i see nice food! I just can't control my mouth!
