Today, the hoe-shaped black pattern we call "spades" represents olive leaves, that is, leaves in the mouth of a dove of peace. The story of the dove of peace can be found in Genesis. This flower means peace. "Heart" is a heart, symbolizing wisdom and love. The third pattern "Plum Blossom" has three black leaves, which come from a common grass-clover. This kind of grass has three petals on one leaf, and occasionally four petals, but it is rare. According to European and American customs, whoever finds a four-petal clover will take "luck", so clover represents happiness. The "square" of a diamond is actually the shape of a diamond, which means wealth.

Poker is the epitome of a calendar. It is said that it was compiled by predecessors according to the knowledge of seasons. Four kinds of flowers represent the four seasons of a year: spring, summer, autumn and winter. Spades represent leaves sprouting in spring, hearts of peaches mature in summer, plums represent fallen leaves in autumn, and squares are like ice in winter. These four colors are people's best wishes in a year. At the same time, hearts and diamonds represent the day, while spades and clubs represent the night.
