Why does peach blossom have the metaphor of "beauty is unlucky"?

This may be related to the characteristics of peach trees. According to the Chronicle of Wen Zhenheng in Ming Dynasty, "Peach bears fruit early and withers for ten years, so it is called short-lived flower." It is said that peach trees are precocious and can bear fruit in three years, but they will age in six or seven years, and then the branches will become thinner and thinner. It is easy to wither after more than ten years, and its age is not long, and it is even called "short-lived flower". Therefore, the ancients wrote poems that "plums are sour-hearted trees and peach blossoms are short-lived branches".

This may also be related to mysterious cultural factors in China traditional culture. Mysterious culture pays attention to geomantic omen, physiognomy and fortune telling. The eight-character numerology of "peach blossom" and the five senses of "unlucky beauty" are vague and ambiguous. Li Yu said that whenever a woman's face is similar to a peach blossom and the color is indistinguishable, she should regard it as a flower soul, and she can be judged that she is not far from death. But don't say it, lest she be sad. It is absurd for Li Yu to judge a woman's life and death by her appearance.

This may be related to the literati following the literary image of "peach blossom = beauty is unlucky". Beauty is easy to age and beauty is easy to decline, which has long been the theme of many poems related to peach blossom. "Peach Blossom with a Face" has become a symbol of sadness and pain in the hearts of sentimental literati, thus leaving a painful beauty with endless aftertaste. The common image of "falling red" in literary works has rendered countless sorrows. Once love is compared to peach blossom, there is always a little bitterness behind beauty. Peach blossom is easy to wither, beauty is easy to get old, flowers bloom and fall, and it is natural to regret when spring returns to the earth. Sighing for the misfortune of beauty has become the sad mood of literati.
