The early playing cards may have been introduced to Europe from Egypt at the end of the 14th century.

In the 15th century, K is usually considered to be a big card, and A is a small card. The current way of treating A as big and 2 as small may have started after the French Revolution in the late 18th century. "Joker" (JOKER) was an American invention, and then returned to Europe with poker.

Two decks of cards represent the sun, the cat represents the sun, and the kitten represents the moon; peach, heart, square, and plum respectively represent the four seasons of spring, summer, autumn and winter. The red card represents the day and the black card represents the night; each season 13 weeks, the number of cards in each set of poker is exactly 13, and the sum of the points of the 52 cards is 364. Plus the points of the kitten is 365. It is the same as the number of days in a normal year. ; If you increase the number of cats a little, it is exactly the number of days in a leap year. There are 12 K, Q, and J playing cards, which not only means that there are 12 months in a year, but also means that the sun passes through 12 constellations in a year.
