For newbies who are new to mahjong, the most commonly asked question is "What is mahjong?" In fact, Hu cards are not as complicated as you think. As long as you master the basic card type combinations and rules, you can quickly get started. This article will provide you with a detailed breakdown of the conditions, common card types and special Hu methods in an easy-to-understand way, helping you thoroughly understand the Hu logic of Mahjong.

1. Basic conditions for Mahjong

Simply put, Hu cards are the combination structure of your hand that meets the regulations. In most Mahjong games, a deck of Hu cards is usually composed ofFour sets of faces (straight or cut) plus a pair of trump cards (also known as sparrow heads)组成，总共14张牌。这里的“面子”指的是三张连续的牌（顺子）或三张相同的牌（刻子），“将牌”则是两张完全相同的牌。

例如，你的手牌是：1万2万3万、4条5条6条、7筒7筒7筒、东东东、5万5万。这手牌就符合“4组面子+1对将牌”的结构，因此可以胡牌。需要注意的是，不同地区的麻将规则可能略有差异，但这一基本结构是通用的。

二、常见的胡牌牌型详解

1. pinghu

平胡是最基础的胡牌方式，由四组顺子（或刻子）加一对将牌组成，没有特殊限制。例如：123万、456条、789筒、234条、55万。只要牌型结构正确，就可以胡牌。

2. Pengpenhu

碰碰胡要求四组面子全部是刻子（三张相同的牌），加上一对将牌。例如：111万、333条、555筒、999万、77条。这种牌型因为全是刻子，看起来很有气势，胡牌后番数通常较高。

3. exclusively

清一色是指整副牌全部由同一种花色的牌组成，可以是万、条、筒中的任意一种，且不能包含字牌（东南西北中发白）。例如：123万、456万、789万、234万、55万。清一色是典型的高番牌型，但做牌难度也较大。

4. seven pairs

七对是一种特殊的胡牌牌型，由七个对子组成，不需要顺子或刻子。例如：11万、33条、55筒、77万、99条、22筒、44万。七对胡牌时手牌共14张，且每个对子都必须是两张相同的牌。需要注意的是，有些规则中七对不允许有重复的对子（即豪华七对），但基础七对通常允许。

3. Special Hu Paying Method

In addition to the above common card types, there are also some special tricks in Mahjong. Understanding them can make you more flexible in actual combat.

  • self-drawn: The cards you touch are just enough to play, and you don't need others to click.
  • fire: The cards played by others are exactly the cards you need. You can choose the cards.
  • flower on the bar: The card you draw after the card is exactly the right card.
  • snatch a beard: When others add a card, you can just play that card.
  • for the moon: The last card on the card wall touches Houhu card.

4. Common misunderstandings among novices

Many novices easily make the following mistakes when judging "what mahjong is a hoot":

  1. Forget the trump card: Hu cards must have a pair of trump cards. If there are only four sets of faces and no pairs, you cannot play.
  2. Imcomplete face：顺子必须是连续的三张同花色牌，刻子必须是三张完全相同的牌，不能混搭。
  3. Wrong number of cards：胡牌时手牌必须是14张（杠牌除外），多一张或少一张都不行。
  4. Ignore special rules：不同地区可能有特殊限制，比如某些玩法不允许“全求人”或“无字牌”，需要提前了解。

五、如何快速判断是否胡牌

In actual combat, you can quickly check your hand by following these steps:

  1. Count the number of cards first and confirm whether there are 14 cards (or the corresponding number behind the bar).
  2. Try dividing your hand into four groups of faces and a pair of general cards. You can give priority to finding pairs as general cards.
  3. 如果无法拆出标准结构，再考虑七对等特殊牌型。
  4. 结合当地规则，确认是否有额外限制。

By mastering these methods, you can quickly determine whether you have a card at the table and avoid missing opportunities to play a card.
