To control and pull in battle. Derivative of a very old chinese kata probably originally from the Hsing-I system.

The name "Seiyunchin" is derived from the Chinese characters for "calm mind, persevere and advance," which reflects the focus and control required to execute the techniques in the kata. Seiyunchin is known for its long, fluid movements and relaxed, natural stances. It is typically taught to intermediate or advanced students who have already mastered the basics of Goju-ryu karate.
