Wing Chun Trapping??

I know wing chun is about occupying the centerline, so there must be some good traps to get to the centerline, can someone describe some?(i dont speak chinese, so pak sao n stuff wont help)…jes curious how trapping works

You don’t “trap to get to the center line”. You hit the center line; and only ‘trap’ if somethings in the way. Move it out of the way so you can keep on hitting the centerline.

You first have to ask yourself why you want to get to the centreline?
