A Chinese martial art (4,2)
I believe the answer is:
kung fu
'a chinese martial art' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for kung fu that I've seen before include "Unarmed Chinese martial art" , "Chinese system of unarmed combat like karate" , "Chinese form of unarmed combat, was a TV serial" , "fighting" , "Chinese type of karate" .)
