What does the "square" in playing cards symbolize?

What does the "square" in playing cards symbolize? Answer: In the early days of wealth, playing cards popular in European upper class were all made by hand. /kloc-after the 0/5th century, with the development of printing, playing cards began to be made by printing, which made them widely spread among the people. In the early days, the number of playing cards varied from country to country, such as 22 in Italy, 32 in Germany, 40 in Spain and 52 in France. Today, we can still see more playing cards from these countries. At present, the 54 cards we usually see are evolved from the 52-card model that appeared in France in 1392, that is, Waida and Xiaowang. Later, the number of playing cards in various countries gradually unified into the current 54-card model. Playing cards are divided into four colors: spades, diamonds, clubs and hearts. People all over the world give different cultural explanations to the four colors with their own national cultures. The French understand the four colors as spear, square, clove leaf and red heart; Germans understand the four colors as leaves, bells, acorns and hearts. Italians understand the four colors as swords, coins, crutches and wine glasses; The Swiss understand the four colors as acorns, bells, flowers and shields; The British understand the four colors as shovel, diamond, clover and red heart. 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 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. The 54 patterns of playing cards are also wonderful to explain: the king represents the sun, Xiao Wang represents the moon, and the remaining 52 cards represent 52 weeks in a year; Heart-shaped, diamond, plum blossom and spades symbolize spring, summer, autumn and winter respectively. There are 13 cards in each suit, which means there are 13 weeks in each season. If J, Q and K are regarded as 1 1, 12, 13 points, then the king and Xiao Wang are half points, and the total number of points in a deck of playing cards is exactly 365 points. In leap years, Wang and Wang calculate 1 point and ***366 points respectively. Experts generally believe that the above explanation is not a coincidence, because the design and invention of playing cards are inextricably linked with astrology, divination, astronomy and calendar. J, Q and K in playing cards are abbreviations of attendants, queens and kings in English, and 12 head cards respectively represent someone in history: K of spades is David, the father of Solomon, king of Israel in the 10 century BC. He is good at playing the harp and has written many hymns in the Bible, so the picture of spades K often has the pattern of the harp. K of hearts is King Charles I Frank. His name is scharmann, and he is the only one of the four trump cards who doesn't need a king. King Caesar, the king of the Roman Empire, a famous soldier and politician, is the only silhouette among the trump cards of the Four Kingdoms. K of clubs is Alexander, the first Macedonian king to conquer the world. He always wears jewels with crosses on his clothes. Q of spades, Greek wisdom and Sivir pallas Acina are the only queen with weapons among the four queen cards. Q of hearts and Q of diamonds are Jules and Queen Raquel respectively. The name of plum blossom Q is Akini, which comes from the word "Regina". She holds a wild rose in her hand, indicating that the Lancaster royal family symbolized by the red wild rose and the York royal family symbolized by the white wild rose finally reconciled after wars of the roses, and tied the wild roses of both sides together. The J of spades and the J of diamonds are Hokkala and Roland, the attendants of Charles I, respectively. J of hearts is Lahaiya, Charles VII's attendant. J of clubs is Lancelot, a famous knight in King Arthur's story. In recent years, many countries have printed representative pictures reflecting their own culture, folk customs and styles on poker.
