What does the square card mean?

Square cards refer to playing cards with square patterns.

The diamond, also known as the diamond, is one of the four colors (plum blossom, diamond, heart and spades) in playing cards. This square is in the shape of a diamond, symbolizing wealth. In playing cards, one suit is called diamonds, and the other three are called hearts, spades and clubs.

Why to use these four patterns as the patterns and colors of playing cards has been said a lot. There are two kinds of centralized views: one is that these four colors represent the four major industries of society at that time, among which spades represent spears, soldiers and death; 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.
