Fānziquán" 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.

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

The complete system of Fānziquán of Hebei province is rarely practiced today. The Dongbei Style of Fānziquán is the most popular and was also the basis on which the Modern Wushu Fānziquán 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 Fānziquán, includes a set of Xingquan and Lianquan 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 Fānziquán. The Mianzhang style (Duanquan) was combined with HebeiFanzi to create the style MianzhangFanzi.

In modern times, Fānziquán is often taught in conjunction with Chuojiao not unlike how Xingyiquan and Baguazhang 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 Fānziquán, with their more compact movements combining soft and hard power, were known as Scholarly Routines, which is why the Chuōjiǎo/Fānziquán 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.
