Khanhoo Khanhoo or Kanhu is a non-partnership Chinese card game of the draw-and-discard structure. It was first recorded during the late Ming dynasty as a multi-trick taking game, a type of game that may be as old as "T'ienkiu" ("Heaven and Nines"), revised in its rules and published in an authorized edition by Emperor Kao Tsung in 1130 AD for the information of his subjects. Meaning "watch the pot", it is very possibly the ancestor of all rummy games.
