Today, I lost seven cards in a deck of playing cards. I don't know what that means.

A deck of playing cards * * * has 54 cards and 13 numbers. Each number has 4 cards and 4 colors, namely spades, hearts, clubs and diamonds. Represents the spring, summer, autumn and winter of the year. Spades and clubs are black, indicating night, and hearts and diamonds are red, indicating day.

Card point:

Are these four colors spades? (Spades, also known as sunflower fans), hearts? (heart, also known as red heart), plum blossom? (Dong Jia, also known as Caohua), diamonds? Diamond, also called stepping brick or square, is called "Ba Block" in Sichuan and Chongqing. Spades and clubs are black, the other two are hearts and diamonds are red. Thirteen cards of each pattern, with numbers from one to ten, English letters J, Q, K, cards from one to ten are represented by the number of patterns, and J, Q, K are represented by head cards.

It is said that these four colors represent the four major industries of society at that time, among which spades represent spears and symbolize soldiers; Plum blossoms represent clover flowers and symbolize agriculture; Square represents bricks used by craftsmen; The heart represents the heart and symbolizes the priest.

On the other hand, these four colors come from the patterns of ancient European divination tools, in which spades represent olive leaves and symbolize peace; Plum blossom is a four-leaf clover, which means good luck; The square is a diamond, symbolizing wealth; The heart shape symbolizes wisdom and love.
