Excuse me: What do black pottery, diamonds and clubs on playing cards represent respectively? ^

Why are playing cards divided into four colors: hearts, diamonds, grass flowers and spades? It symbolizes the four seasons of the year: spring, summer, autumn and winter. So it's not hard for us to figure out why each suit has 13 cards, which means that there are 13 weeks in a season. Wang (commander in chief) represents the sun and Xiao Wang represents the moon. Why is a deck of cards divided into red (hearts and diamonds) and black (flowers and spades)? Now you can see why: red stands for day and black stands for night. Spades represent death, hearts represent love, diamonds represent RP, clubs represent mood, a good hand represents victory, and a bad hand represents bad luck.
