Playing cards are made according to the principle of calendar. What do Big Wang and Xiao Wang represent respectively?

The king represents the sun and Xiao Wang represents the moon.

In a deck of cards, two clowns, one big and one small, represent the sun and the moon, so the remaining 52 cards represent 52 weeks of the year, four colors represent the four seasons of the year, and 13 cards of each color represent 13 weeks of each season. If each suit and number of cards are counted by points, the result of the big clown counting by half points is 365 days in a normal year, and if the big clown counts by one point, it is 366 days in a leap year. Experts generally believe that the above explanation is not a coincidence, because the design and invention of playing cards are inextricably linked with astrology, divination, astronomy and calendar.

Extended data:

Poker usually has 54 cards, two of which are jokers, that is, two cards called the king of size. In fact, these two cards did not exist at first.

The traditional cards with the colors of spades, hearts, clubs and diamonds were invented by the French in the14th century, with only 52 cards at the beginning. Around 1850, some poker manufacturers began to add the 53rd card to their cards. At that time, this card was only used as a replacement card or as an advertisement. At that time, this card was not called JOKER, but called "extra card", which means extra card.
