Fight the Landlord (Dou Di Zhu) is a climbing game primarily for three players, but also playable by four. In each hand one player, the "landlord", plays alone and the others form a team. The landlord's aim is to be the first to play out all his cards in valid combinations, and the team wins if any one of them manages to play all their cards before the landlord. The game is said to have originated in Hubei province but is now popular all over China, and is also extensively played on line.

This game's rule is based on the QQ online Game: Happily Fight the Landlord, which is very popular in China.
