Fanziquan

Fanziquan "Rotating fist" emphasizes offense and defence with the hands. Its movements have been described as:

Two fists are fast like the falling raindrops, and fast like a snapping whip.

Fanziquan routines are usually quite short and very fast. It is a source of many other modern styles like Eagle Claw.

The complete system of Fanziquan of Hebei province is rarely practiced today. The Dongbei Style of Fanziquan is the most popular and was also the basis on which the Modern Fanziquan routines have been based. Elements or parts of Old BāfānMén (Fanzi) have been spread under many banners. Liu DeKuan taught a set of Ba Fan Shou in Beijing which has been practiced by his descendants. The Eagle Claw style, which is a derivative of Fanziquan, includes a set of Xingyiquan and which are said to be the essence of the style and are based on some parts of BāfānMén. The Ma Family Tongbei System of North Western China includes the Dongbei variants of Fanziquan. The Mianzhang style (Duanquan) was combined with HebeiFanzi to create the style MianzhangFanzi.

In modern times, Fanziquan is often taught in conjunction with Chuōjiǎo, not unlike how Xíngyìquán and Bāguàzhǎng are often taught together. The routines of Chuōjiǎo, with its kicks, wide open stances and focus on hard power, were known as Martial Routines and those of Fanziquan, with their more compact movements combining soft and hard power, were known as Scholarly Routines, which is why the Chuōjiǎo/Fanziquan combination is known as Wen Wu or Martial-Scholar.

Throughout history, BāfānMén's techniques have been admired by many masters and as a result it is often recognized as Muquan, or Mother Fist, in representing how essential it is to the Chinese Martial Arts.
