Seisan Seisan The karate kata (alternate names Sesan, Seishan, Jusan, Hangetsu) literally means '13'. Some people refer to the kata as '13 Hands', '13 Fists', '13 Techniques', '13 Steps' or even '13 killing positions'. However, these names have no historical basis. Seisan is thought to be one of the oldest kata, being quite spread among other Nahate schools. Shito-ryu has its own version and different versions are now practised even in Shuri-te derivatives like Shotokan (called Hangetsu) and in Wado-ryu (called Seishan). Isshin-ryū also adopted this kata. This kata is also practiced in Korean styles such as Tang Soo Do and
Ryu Seung-soo (2013). Despite being one of his earliest projects, the 2002 melodrama "Winter Sonata" is among Ryu's better known roles outside Korea, given the series' popularity throughout Asia. In 2009, he reprised his character via voice acting in the animated adaptation "Winter Sonata Anime". Ryu wrote his memoir "Don't Be an Actor Like Me", which was published in 2009. Ryu Seung-soo Ryu Seung-soo (born August 12, 1971) is a South Korean actor. Ryu made his acting debut in 1997 with a minor role in Park Chan-wook's film "Trio", and has been active as a supporting actor on film and television since.
