Ziranmen

Ziranmen (simplified Chinese: 自然门; traditional Chinese: 自然門; pinyin: zìránmén; Wade–Giles: tzu-jan men; literally "the ziran ["natural"] style"), also known as Natural Boxing, is a Northern internal style of kung fu that is taught in conjunction with qigong breathing techniques. The style traces its lineage to Dwarf Xu, who based it on ancient Taoist philosophy. Du Xinwu, the next bearer of the lineage, served as a bodyguard to Sun Yat-sen, then the provisional president of the Republic of China. Du imparted his knowledge of "Natural Boxing" to his eldest son Du Xiusi and Wan Laisheng, a prominent twentieth century martial artist.
