Zheng Shangyou (Chinese: 争上游; pinyin: Zhēng Shàngyóu; lit.

'struggling upstream') is a Chinese shedding card game similar to President and Big Two.

The game uses one or two standard 54-card decks, with thirteen cards in four suits plus two jokers, one red and one black in each.

The dealer (who may be chosen by cutting the cards, as usual) shuffles the deck, to begin with and begins dealing out the cards singly, starting with himself, in a clockwise manner around the table.

When a player plays the red joker as a single/double or a pair of 2s, it is sometimes customary for that player to restart play immediately by leading a new card or combination since the red joker cannot be beaten as a singleton, nor the pair of 2s, and the passes are mere formalities (except in the rare cases of another player having a bomb).

Likewise, for a 3-player game, a player with 17 cards remaining is deducted triple points.
