Wing chun is primarily hands and in-fighting. Just look it up in youtube.
I've done it for couple of years and could easily trapped the hands of other martial artists in sparring.

Most of the styles developed in Northern China or a mountainous region use primarily hand techniques for obvious reasons. Tae Kwon Do and those styles developed in Southern China use more kicking techniques. The Okinawan styles use more hand techniques especially Goju-Ryu.
