Wanshū (ワンシュー, also 腕秀 and 汪輯) is the name of several katas in many systems of karate, including Isshin-Ryu, Shotokan (under the name empi), Wadō-ryū, and others. The name Wanshū (腕秀) in Mandarin means "Excellent Wrist" and refers to a typical technique of this form. The other way of writing the name of this kata (汪輯) means "Wang's Series (or Form)" and refers to the name of the diplomat Wang (1621 – 1689),. Wang was the leader of a large ambassadorial mission from China sent by the Qing government in 1683 to the village of Tomari. A poet, calligrapher, diplomat, and martial artist in the Shaolin tradition of Fujian White Crane, he is often credited with teaching chu'an fa to the gentry of Tomari.
