The Vinegar Tribe (2005)

Xiao Bai and Xiao Hong are two long-lost siblings whose parents had passed away. However, their reunion is not all happy and cheery. Since they never got along as kids, they fight like cats and dogs as adults and refuse to live peacefully together like civilized people do. They finally make a pact that whoever gets married first can continue to live in their father’s house while the other must move out. So, they begin their individual quests to find Miss and Mister Right.
