Gojushiho is an old kata that is mentioned in the Bubishi (Old Chinese martial arts text). The name means "Fifty four steps" and is referred to in the Bubishi as "Fifty-four Steps of the Black Tiger". The kata really shows the Chinese influences with it's many circular hand movements, finger striking techniques and fluid nature.
Some versions of the kata contain a "drunken" staggering type movement, although, this movement doesn't occur in the Matsumura version.
Useishi is usually called Gojushiho, which means 54 steps whose movements are said to resemble a drunken man.
