Yuen Siu Tien (袁小田) (1912–1979) (also known as Yuan Xiao Tian, Simon Yuen, Sam Seed or "Ol' Dirty") was a kung fu movie star in the 1970s. He starred in films with actors like Jackie Chan and under the direction of his son Yuen Woo-ping. He died of a heart attack in 1979.
Yuen featured in over 35 films throughout his career. He reprised the role of The Beggar So for three further films, Dance Of The Drunk Mantis, Story Of Drunken Master and a cameo in World Of The Drunken Master. He was cast to play the role again, in Magnificent Butcher with Sammo Hung, but died part way through filming. On the previews for the film they had promised a return of the Drunken Master but he was actually replaced by another actor, Fan Mei Sheng. Filming continued with Fan's Drunken Master character, including re-shooting some of Yuen's scenes. However, Fan's character is never referred to by the names Su Hua Chi or Beggar So in the film.
Yuen Siu Tien's likeness was used for the character Chin Gentsai in the SNK series, The King of Fighters as well as for the character Shun Di from the Virtua Fighter series (taken from the role of Su Hai from Drunken Master).
