1. A blessing in disguise comes from "Dongxuan Notes".

2. "Dongxuan Notes" is an ancient Chinese classical Chinese anecdotal novel written by Wei Tai, the author of the Northern Song Dynasty. I believe many people have learned the allusion about a blessing in disguise. It tells the story of an old man living outside the Great Wall who lost a horse, and then the lost horse brought back another good horse. Therefore, there is also a wise saying that a blessing in disguise is a blessing in disguise. It warns people not to be too concerned about gains and losses, but to look at some of the things they have lost with good expectations. This contains the great wisdom that what is lost is what is gained. In daily life, we really need such an optimistic and open-minded attitude to face the gains and losses in our growth process.
