Several problems about playing cards

There are 32 playing cards in Rank 9, namely:

Heaven, Earth, Man, Harmony (Goose), Plum Blossom, Changsan 6, Bench 4, Black 1 1 (or Axe/Tiger Head), Red Head 10, Tall Foot 7, Bronze Hammer 6, one pair each. Za 9 (divided into white 9 and red head 9, with the same usage), Za 8 (divided into flat head 8 and inclined head 8, with the same usage), Za 7 (divided into white 7 and red head 7, with the same usage), Datou 6 (1), Za 5 (divided into white 5 and red 5, with the same usage), Ding 3 (1).

Pai Jiu Pai is said to have been designed and presented to the emperor by a minister in the second year of Xuanhe, Song Huizong. In the Southern Song Dynasty, Zhao Gou, Emperor Gaozong, was partial to the south of the Yangtze River and promulgated the imperial edict of "having fun with the people" to the world. So the ninth row is the most popular in Jiangnan. There are nine rows of 32 cards in each deck, and the front of each card consists of the points of two dice. For example, two sixes make up a "heavenly card", two twos make up a "land card", two fours make up a "human card", and one threes make up a "safe card".

Except that 24 plus 22 can form the largest pair of "Supreme" with different points, the other pairs must have the same points. In addition to the harmony of heaven and earth mentioned above, it also has plum blossom (two fives), gown (two threes), bench (two twos), axe (five plus six), chuck (four plus six) and bronze hammer (one plus six).
