In contrast to Europe, Chinese trick-taking games did not develop trumps or bidding. They diverged into multi-trick games where melds can only be beaten by other melds provided they have the same number of cards. During the Qing dynasty, these multi-trick games evolved into the earliest draw-and-discard games where the players' objective is to form melds and "go out" rather than capturing the opponents' cards. Khanhoo is an example of a multi-trick game that became a draw-and-discard game. Multi-trick games are also probably the source for climbing games like Winner and "dou dizhu" which first appeared during the Cultural Revolution.
