Martial arts with trapping?

[Mtal]

I was wondering what martial arts out there have a lot of trapping in it? I know Wing Chung and JKD have them. Are there any other styles out there I can look into.

Many Filipino styles have this too, especially for weapons work!

Other Southern Chinese styles will also have some of it, though Wing Chun is certainly well known for trapping.

[Steel Tiger]

Many Chinese arts involve trapping. It is particularly prevalent in the internal styles like xingyi, bagua, and taiji. Bai Mei also involves trapping. Then, of course, there is qinna.

[CuongNhuka]

Cuong Nhu includes trapping, but is an advanced concept, and most schools don't really stress it too much. We also do jamming (trapping a leg), but it is similar to trapping.
May I ask why you ask?
