The four gentlemen in the flower refer to:
Spring orchids, whose flowers are light in color, fragrant and clear, are often born in secluded places, so they are often regarded as a symbol of modest gentlemen. Summer bamboo, after a cold winter, does not wither, and has its own beauty. It is upright, modest, neither arrogant nor humble, and unrestrained. It is often regarded as a symbol of distinguished and elegant people. Autumn chrysanthemum is not only elegant and fragrant, but also beautiful after the withering flowers. It does not compete with other flowers, so it has always been used to symbolize the noble character of being calm and unyielding. Winter plum blossom, which opens against the cold, is extremely beautiful and vulgar, and has the characteristics of being brave and brave. It is a symbol of indomitable personality.
