Each has his own regrets. "Fireworks have their own regrets" is a famous saying in China's ancient literary masterpiece A Dream of Red Mansions. This sentence comes from Jia Baoyu. The original text is: "now we understand that the pain of life is just fireworks, and each has its own regrets." Life is short, like fireworks, leaving a beautiful moment in life, but then it disappears. Everyone has their own regrets and disappointments, which is inevitable. This famous saying expresses a profound understanding of the shortness and imperfection of life, and also reflects the understanding and aesthetic taste of life in China traditional culture.
