Chinese martial arts , often named under the umbrella terms kung fu -LRB- -LSB- ˈkʊŋ_ˈfuː -RSB- -RRB- and wushu , are the several hundred fighting styles that have developed over the centuries in China . These fighting styles are often classified according to common traits , identified as `` families '' , `` sects '' or `` schools '' of martial arts . Examples of such traits include Shaolinquan physical exercises involving Five Animals mimicry , or training methods inspired by Chinese philosophies , religions and legends . Styles that focus on qi manipulation are called internal , while others that concentrate on improving muscle and cardiovascular fitness are called `` external '' . Geographical association , as in northern and `` southern '' , is another popular classification method .
