When playing mahjong, the most common question asked by many novices is: "What card is bad when playing mahjong？”In fact, Hu card does not refer to a specific card, but means that the combination of cards in your hand conforms to the prescribed card structure. Simply put, when your hand can form a specific combination of cards and meet the basic conditions, you can declare a card. This article will analyze the basic rules, common card types and some special Hu methods in detail to help you quickly master Hu card skills.

胡牌的基本条件

In most mahjong rules, Hu cards need to meet the following basic conditions:

  • Number of cards in hand: Usually 14 cards (including a card that has just been touched or played by someone else).
  • Card type structure: It consists of four sets of faces (straight or carved) and a pair of general cards, called "basic hu".
  • 没有违规：例如没有“相公”（多牌或少牌），没有“诈胡”（不符合胡牌条件却宣布胡牌）。

面子分为两种：顺子（例如：3万、4万、5万）和刻子（三张相同的牌，例如：三个东风）。将牌则是一对相同的牌，例如两个红中。

常见胡牌牌型

除了基本胡，麻将中还有许多特殊牌型，它们往往有更高的番数。以下是一些常见的胡牌牌型：

pinghu

Pinghu is the most basic method of playing cards. It consists of four sets of straight and a pair of general cards, and there are no notches or bars. For example: 1.23 million, 456 pieces, 789 barrels, 2.34 million, a pair of 5 pieces. Pinghu is usually low in number but easy to achieve.

Pengpenhu

Touping Hu consists of four sets of chips (or bars) and a pair of trump cards, with no straight. For example: three east wind, three 50,000, three 8, three 2 cylinders, a pair of 90,000. The number of times of Dampenhu is usually higher than that of Pinhu.

exclusively

清一色是指手牌全部由同一种花色的牌组成（万、条、筒中的一种），且符合基本胡牌结构。例如：123万、456万、789万、333万、一对5万。清一色是较高番数的牌型。

seven pairs

七对是指手牌由七个对子组成，没有顺子和刻子。例如：11万、55万、88条、33条、99筒、22筒、77筒。七对在某些规则中需要门清（没有吃、碰、明杠）。

mixed color

Mixed color is a Hu card type composed of one color card and character card (white in the southeast, northwest and middle). For example: 1.23 million, 4.56 million, 7.89 million, Dongfeng carved son, a pair of red medium. The number of songs mixed in one color is usually higher than that of Pinghu but lower than that of one color.

Special Hupai Method

除了上述牌型，还有一些特殊的胡牌方式，它们不遵循基本牌型结构，但同样可以胡牌：

Thirteenth one

The thirteen ones are composed of one card of each of thirteen types of 19 cards (10,000, 90,000, 1, 9, 1 barrel, 9 barrel, and middle white in southeast, northwest and middle hair), plus any one of them to form a pair. For example: 10,000, 90,000, 1 line, 9 line, 1 line, 9 line, east, south, west, north, middle, hair, white, plus one white. Thirteen 11 is an extremely tall foreign species and is very rare.

flower on the bar

Blooming on the bar means that when you open the bar and replenish the cards from the end of the card wall, the cards you receive will just make you win the cards. This kind of hustle usually has extra points.

for the moon

海底捞月是指当牌墙只剩最后一张牌时，你摸到这张牌并胡牌。同样，如果别人打出最后一张牌你胡牌，则称为“河底捞鱼”。

如何判断自己是否胡牌

要快速判断是否胡牌，可以按照以下步骤：

  1. Check whether the number of cards in your hand is 14 (or meets current rules).
  2. Try breaking down your hand into four sets of faces and a pair of trump cards. You can first find a pair as a trump card, and then see whether the remaining cards can form a straight or a cut.
  3. 如果无法分解为基本牌型，检查是否满足特殊牌型（如七对、十三幺等）。
  4. 确认没有违规，如多牌少牌、错吃错碰等。

多加练习后，你会逐渐熟悉各种牌型，判断速度也会提高。

常见误区

  • 以为胡牌是某张特定牌: Hu card does not refer to a certain card, but refers to the card type combination that conforms to the rules.
  • Ignore special card types：有些玩家只关注基本胡，而错过了七对、清一色等更高番数的牌型。
  • 忘记将牌：基本胡必须有一对将牌，缺少将牌不能胡牌。

Anyway,What card is bad when playing mahjong取决于你的手牌组合是否符合规则。掌握基本牌型和常见特殊牌型，并在实战中灵活运用，你就能更自信地判断胡牌时机。希望本文能帮助你更好地理解麻将胡牌规则，享受麻将的乐趣！
