In some rules, 4 must not be handed until the player gets point. If a player handed 4 without having a handing of pure Gou Ji cards not followed by head rival, or in some variants handed 4 partially or together with 2 or jokers, he is failed to get point in this game. If a player failed to get a 4 after dealing cards, he has to buy several "4" by same number of "2" from any player who able to sell him "4", except having no "2" then get a "4" for free.
