Regret refers to dissatisfaction, regret, unwilling things, and regret arising from uncontrollable or irreversible circumstances. Let me give you an example. For example, you missed a very simple question in the exam and failed, which is your regret. Why is this disgusting and unwanted thing a kind of beauty? Because regret creates more beauty than perfection.
In the Tang Dynasty in China, there was a famous poet-Li Bai, who was known by almost all China people. Li Bai's poems are naturally lively, unrestrained and fresh, elegant and smart, with rich imagination, wonderful artistic conception, wonderful language, romance and clear artistic conception. It is a treasure of Chinese civilization to express endless feelings in concise and lively language.
But such an extraordinary Li Bai, like many people, has regrets all his life. Li Bai prides himself on being an unrivaled talent, boasting the achievement of "strengthening his wisdom and helping him to make the Atlas area big and the sea county clear". Throughout his life, he has been unswervingly pursuing the ideals of "laughing at Li Yuan" and "enjoying the country at last", that is, being a big official, governing the country and leveling the world.
But did he finally do it? Actually, it's not. In fact, he entered the palace in the first year of Tianbao, which was the beginning of the decline of national strength in the Tang Dynasty. Being praised by the princess and He, the emperor called Li Bai into the palace. But he asked Li Bai to be an official, not to govern the country, but to write poems for himself. So in fact, Li Bai didn't get any management position until the war.
But it is precisely because of his frustration that he created so many poems and articles. Isn't this the beauty brought by regret? If he has no regrets and becomes an official, how can he have time to enjoy the mountains and rivers?
The beauty brought by regret is not only Li Bai, but also many artistic and scientific achievements. The beauty of regret is precisely because he has brought progress to the world.
