Plum is native to southern China and has been cultivated for more than 3000 years. There are many varieties of plum, whether it is ornamental or fruit trees. Many types are not only cultivated in the open field for viewing, but also planted as potted flowers to make plum piles. Flowers can be refined, and flowers, leaves, roots and seeds can be used as medicine. The fruit can be eaten, pickled or processed into Senecio scandens, or smoked into ebony, which has the effects of relieving cough, stopping diarrhea, promoting fluid production and quenching thirst. Plum blossom can resist the harm of root-knot nematodes and can be used as the rootstock of drupe fruit trees.

Plum blossom is the first of the top ten famous flowers in China. Together with orchids, bamboos and chrysanthemums, they are called "four gentlemen", and together with loose bamboo, they are called "three friends in cold years". 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.
