On the mahjong table, there is sometimes an amazing situation: players have just finished drawing the cards and have not played a card before they directly announce the cards. What is this kind of "mahjong is stupid"? In fact, this is the famous "Tianhu" in Mahjong, also known as "Tianhe" or "Tianting". Tianhu is one of the luckiest card types in mahjong, and the probability of appearing is extremely low, so whenever someone has Tianhu, it will become the focus of the table.

What is Tianhu?

Tianhu, as the name suggests, is a "god-given Hu", which means that after the player starts to match the cards, he has already met the conditions for a Hu card before playing any card. In most mahjong rules, Tianhu is limited to the dealer, because the dealer starts drawing 14 cards, while the player only has 13 cards, and you need to touch one card to win the cards. If a player listens to the cards after starting with 13 cards, and touches his own card during the first card draw, it is called "Dihu". Therefore,"what's it if you go wild together with mahjong" usually refers to the banker's talent.

Differences in Tianhu's rules

Mahjong rules in different regions have different identification and scoring of Tianhu:

  • National standard Mahjong: Tianhu is one of the highest varieties, with a total of 88 varieties. The dealer is required to start with 14 cards, namely, Hu cards, and must not eat, touch, or bar.
  • Japanese Mahjong: Tianhu is a full-card type. The dealer's starting card is a Hu card. The probability is extremely low, about 1 in 330,000.
  • Guangdong Mahjong: Tianhu is usually counted as the largest number. In some ways, Tianhu can directly win the cap points.
  • Sichuan Mahjong: Some regions recognize Tianhu, but the rules may be slightly different, and some requirements must be lacking to achieve Tianhu.

How low is the probability of Tianhu?

The probability of Tianhu is one of the lowest among mahjong. Taking the standard 136 cards (excluding cards) as an example, the number of combinations of the dealer's starting 14 cards is about 3.26×10^18, and the number of combinations that can form a Hu card type is relatively small. According to calculations, the probability of Tianhu is about 1 in 330,000, which is far lower than the probability of winning the jackpot in the lottery. Therefore, many mahjong enthusiasts may not encounter Tianhu even after playing poker all their lives.

Factors affecting the probability of Tianhu

The probability of Tianhu is affected by many factors:

  1. Type and quantity of mahjong tiles: The number of mahjong tiles in different regions is different, such as 136 tiles, 144 tiles, etc. The more tiles, the lower the probability of Tianhu.
  2. Hu Pai Rule: Some rules require that one door must be missing, no sign, etc., which will reduce the possibility of a tiger.
  3. Quality of the starting hand: The tidier the starting card, the easier it is to form a Hu card shape. However, Tianhu requires complete formation, which is extremely difficult.

Tianhu's practical skills and mentality

Although Tianhu mainly relies on luck, it is still important to understand some skills and adjust your mentality:

  • quickly judge: After starting, quickly judge whether you have the necessary conditions to avoid missing opportunities.
  • stay calm: Tianhu is an unexpected joy. Don't let excessive excitement affect the subsequent game.
  • know the rules: Before starting the game, verify whether local rules recognize Tianhu and how to score.
