There are hundreds of different styles of Chinese martial arts, each with their own sets of techniques and ideas. The concept of martial arts styles appeared from around the Ming dynasty (1368-1644). Before the Ming period, martial skills were differentiated only by their lineage. There are common themes among these styles which allow them to be grouped according to generalized "families" (Chinese: 家; pinyin: jiā), "sects" (Chinese: 派; pinyin: pài), "class" (traditional Chinese: 門; simplified Chinese: 门; pinyin: mén), or "schools" (Chinese: 教; pinyin: jiào) of martial art styles. There are styles that mimic movements from animals and others that gather inspiration from various Chinese philosophies or mythologies. Some styles put most of their focus into the belief of the harnessing of qi energy, while others concentrate solely on competition or exhibition.
The rich variety of styles has led to the creation of numerous classification schemes. Geographical location such as regional affiliation is one well-known example. A particular Chinese martial arts style can be referred to as either a northern fist (Chinese: 北拳) or a southern fist (Chinese: 南拳) depending on its point of origin. Additional details such as province or city can further identify the particular style. Other classification schemes include the concept of external (Chinese: 外家拳) and internal (Chinese: 内家拳). This criterion concerns the training focus of a particular style. Religious affiliation of the group that found the style can also be used as a classification. The three great religions of Taoism, Buddhism and Confucianism have associated martial arts styles. There are also many other criteria used to group Chinese martial arts; for example, imitative-styles (Chinese: 像形拳) and legendary styles; historical styles and family styles. Another more recent approach is to describe a style according to their combat focus.
