If you add up all the points of 54 cards, you can further prove the relationship between playing cards and calendars. If "J" is eleven o'clock, "Q" is twelve o'clock, and "K" is thirteen o'clock, Wang and Xiao Wang each count half points, and the points of 54 cards add up to exactly the total number of days in the whole year. The design of big and small trump cards also makes sense. 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.
