Seiyunchin - To Pull, Grasp and Unbalance:

Seiyunchin is a long and strength-sapping kata. It contains pulling and gripping techniques, throws, hidden techniques and requires a strong upper and lower body, good breath control and lots of stamina. There are NO kicks in this kata!! This kata is most performed at tournaments throughout the world. The techniques are well suited for practical, close-in fighting.
Seiyunchin kata demonstrates the use of techniques to unbalance, throw and grapple, contains close-quartered striking, sweeps, take-downs and throws. Though the kata itself is devoid of kicks, many practitioners make the grave mistake by missing the opportunity to apply any leg technique, not discovering a "hidden bunkai" in it. Though almost invisible to the untrained eye, the subtleness of ashi barai and suri ashi can represent footsweeps, parries and traps. The centrepiece of seiyunchin kata is a stance taken directly from the White Crane style.
