Each player touches the cards in order, starting with the dealer, 14 cards will be touched, and the leisure family will touch 13 cards. Everyone is eagerly waiting for the first card to appear!

　　How to roll the dice? When we roll the dice, the number of points added by the two dice determines the position of holding the cards, and the smaller dice will tell you where to start holding the cards. Simple, right? After touching the cards, it is the dealer’s turn to play the first card, and then each player touches the cards and plays cards in turn. Remember, you have to take a new card from the pile after the leverage!

　　Playing card type analysis is also the key to getting started with mahjong. There are several main card types that should be paid special attention to: a straight is three cards with the same suit in numerical order, an engraving is three identical cards, and a pair only needs two identical cards. More complicated ones, such as bar cards (four cards are the same) and uniform cards (the whole deck is composed of the same suit), have their own characteristics and are colorful, which makes the world of mahjong so charming.

　　In mahjong, the rules of eating, touching and bumping are also very important. You can only eat one’s cards when you eat, but you can touch three when you touch them, while the bars are divided into open bars and dark bars. These skills are tips for winning in the game. As long as you make good use of them, you will definitely become a mahjong master.

　　How to play Hu cards is also a rule that novice players need to be familiar with. When the cards you catch are combined into a draw, it’s self-touching. And shooting refers to playing the cards needed by the other three. This means that the whole game is full of strategic and psychological contests, which is really unexpected and exciting.
