What are the terms of mahjong?

A card played by an opponent, two cards in his hand can be combined with that card to form a touch card.

For example, if you play one card at home and you have two or three cards, you can eat one, two or three cards, which is similar to a straight card. Play a card after eating a card (something goes in and something goes out).

Note: You can only eat your own cards.

Touch:

If you have two identical cards in your hand, you can touch them.

Example: You have two 50,000 pieces in your hand, and the other party has typed another one. You can touch it. Touch cards and play cards (something goes in and something goes out).

Bar:

When an opponent plays a card, he has three identical cards in his hand, so he can use them.

For example, if you have three 50,000, and someone else hits one 50,000, you can leverage.

PS: You can only eat your family's cards when playing cards. You can touch any card on the bar, and you can draw any card you want, but these three cards are in order, draw cards > touch the bar > eat. For example, if a card from a certain family can be claimed by several families, then draw cards first, draw cards without drawing, and then it is the turn of the person who touches the bar to draw, and the person who touches the bar does not draw.
