Is it a random flop in Guangdong Mahjong?

Yes Guangdong Mahjong flop is a way of playing. In the initial stage of the game, players have the opportunity to uncover a playing card, and the suit of this card will be determined as "ghost card", that is, it is an all-around card with the ability to transform into any required card. After the game starts, each player opens a card in turn, and the suit of the card is set to "ghost card", and then officially enters the game stage. During the game, players can replace any card with ghost cards, but ghost cards can't be used to touch bars or eat cards. When the card in the player's hand and the ghost card form a lettering or straight, the Hu card can be announced.
