Zui Quan

Zui Quan (Chinese: 醉拳; pinyin: Zuì Quán, drunken fist) is a general name for all the styles of Chinese martial arts that imitate a drunkard. It is an ancient style and its origins are mainly traced back to the famous Buddhist and Daoist sects. The Buddhist style is related to the Shaolin temple while the Daoist style is based on the Daoist tale of the drunken Eight Immortals. Zui quan has the most unusual body movements among all styles of Chinese martial arts. Hitting, grappling, locking, dodging, feinting, ground and aerial fighting and all other unsophisticated methods of combat are incorporated.

The technical features of zui quan are based on imitating a drunkard. The main body method is called sloshing, which refers to "Hollow Body, Wine Belly" concept, as though the body is hollow and the lower abdomen (丹田; dantian) is filled with wine (instead of Qi), which travels through the body adding power to the movements. The postures are driven by weight and momentum of the whole body, staggering around, creating sudden power from awkward positions, and fluidity in the movements and transitions from one pose to another. Drunken body style seems peculiar and off-balance, but it is actually in balance.

Drunken style is among the most difficult styles of wushu due to the need for advanced basic requirements. Its intangible, heavy sloshing power is gained through training the body to be soft and agile through basic training and the drunken forms. While in fiction practitioners of zui quan are portrayed as being actually drunk, zui quan techniques are highly acrobatic and require a great degree of balance and coordination, such that attempting to perform these moves while drunk is dangerous, if not impossible.

Drinking, swaying, and falling with great momentum are used to fight. This power must be from softness and heaviness. Even the most unusual parts of the body are actively used to attack and defend. The main hand gesture imitates holding a small cup of wine. This semi-closed hand uses back of the hand, fingers, palms, wrists, forearms, and other parts to attack or defend, grab or throw, lock or release, etc. Fists are rarely used. This style tricks opponents into unpredictable situations of attack and defense. Aerial and ground dodges and falls can be used to avoid attacks but also to pin attackers to the ground while vital points are targeted.
