In actual Mahjong combat, bar cards are a common operation, but many players are interested inWhat's wrong with mahjong?存在疑惑。杠牌后牌型结构发生变化，胡牌规则也有所不同。本文将系统梳理杠牌后的胡牌方式，帮助你理清思路，在牌桌上做出正确决策。

1. Basic types and rules of bar cards

There are three types of bar cards:Minggang、the dark barandmending bar(Also known as plus bars). An open bar is when there are three identical cards in the hand. When other players play the fourth card, they can call "bar" and show three cards; an open bar is when they already have four identical cards in the hand and can be played at any time without showing up. A backup bar is a card that has already been touched, and later touches the fourth card, which can be used to make up the card. After the card is tied, one card needs to be filled from the end of the card wall, and then one card is played, keeping the number of cards in your hand at 13 (or 14, depending on the rules).

二、杠牌后如何胡牌

After the cards are tied, the basic condition for Hu cards is still to form four groups of faces (straight or carved) plus a pair of general cards, or special card types such as seven equal. However, bar cards add additional possibilities. Here are a few common ways to post cards:

1. flower on the bar

flower on the barIt means that when you make up a card after the card, you happen to touch a card that can be played. This is the most direct way to play cards after a card, and there are usually extra rewards. For example, if you make up for a 50,000 card after the card, it will form a Hu card type, and you can announce that the card is blooming on the card. This kind of Hu method requires a certain amount of luck, but it can also increase the probability through card type design.

2. snatch a beard

snatch a beard是指当其他玩家补杠时，你正好可以胡那张补杠的牌。例如，对手已经碰了三万，后来摸到第四张三万并补杠，而你恰好听三万，就可以抢杠胡。抢杠胡的番数通常较高，但需要注意规则：有些地方规定只有补杠可以被抢，暗杠不能被抢。

3. 杠后正常胡牌

杠牌后补牌，如果没有直接胡牌，可以继续打牌，后续通过摸牌或吃碰来调整牌型，最终胡牌。这种情况下，杠牌只是增加了番数，胡牌方式与普通胡牌相同。需要注意的是，杠牌后手牌结构可能改变，要重新评估听牌方向。

3. Strategic adjustments after the card trading

After the poker game, the situation of the game may change, and strategies need to be adjusted in a timely manner:

  • assess risk：杠牌可能暴露你的牌型，让对手提高警惕，也可能为对手提供抢杠胡的机会。因此，杠牌前要权衡利弊。
  • 调整听牌：杠牌后补牌可能改变你的手牌，如果补牌不理想，可能需要改变听牌方向，甚至放弃原计划。
  • 利用杠上开花: If you have already listened to the cards and have the opportunity to directly play the cards after the cards are stacked, you can actively try, but you must also consider the risks of the cards themselves.
  • Prevent grab: Be especially careful when mending the bars. If your opponent may listen to your card, it is best to give up mending the bars to avoid being robbed.

4. Answers to frequently asked questions

1. 杠牌后还能不能胡七对？

可以。杠牌后如果手牌仍然符合七对牌型（即七组对子，杠牌算一组对子），可以胡七对。但要注意，有些规则规定杠牌后不能胡七对，需要事先了解当地规则。

2. How to calculate the number of cards after the card?

The bar card itself will increase the number of times. For example, the open bar will add 1 times, the hidden bar will add 2 times, the flowers on the bar will usually add 1 times, and the grab bar will add 1 times. The specific number of times varies according to local rules, and it is recommended to make it clear before the start.

3. 杠牌后没胡牌，还能继续打吗？

当然可以。杠牌后补牌打牌，牌局继续，你仍然可以正常摸牌、吃碰、胡牌。杠牌只是增加了番数，不影响后续操作。
