1, all Hu cards must be more than 15. Red Hu: When playing Hu cards, the player's cards have red letters greater than or equal to 10, and the order is less than 13, so the interest of all Hu cards is doubled.

2. Thirteen red: when playing Hu cards, there is a red letter greater than or equal to 13, which is counted as 100 Hu Wu; when playing Hu cards, the cards are all black, which is counted as 100 Hu.

3, a little red: there is only one scarlet letter, and the rest are doubled. Yiping: a word in the scarlet letter, a hurdle in the scarlet letter. When it comes to the scarlet letter, all the nonsense is doubled. Self-touch: Double your last breath.
