In the traditional culture of China, what are the two qualities that Mei inspires people to work hard?

Plum blossom is the first of the top ten famous flowers in China. With orchids, bamboos and chrysanthemums, they are listed as four gentlemen, and with pine and bamboo, they are also called "three friends of the old cold". In the traditional culture of China, Mei gives people an incentive to work hard with her noble, strong and modest personality. In the cold, before the flowers bloom, the world is lonely, and spring has come.
