What exactly does "a flash in the pan" mean?

? The idiom "a flash in the pan" means that it will wither soon after a flash in the pan. Now we often use it to indicate that something that is suddenly popular or prominent will die soon, but there is a touching love story behind it.

? A flash in the pan comes from the wonderful lotus sutra? Convenient product 2: Buddha tells Sharifutsu that if it is a wonderful method, all Buddhas will say it when they come. If it is wonderful, they will smell it at first sight. In this case, it is a rare magic method and a metaphor for the accidental appearance of things. Today, we often use it to compare the temporary prosperity of online celebrities or the temporary popularity of an online buzzword. Of course, it will also be used to describe some precious and rare things that are fleeting.

There is also a famous allusion that short-lived stories only belong to Wei Tuo. This story comes from Buddhist scriptures. Legend has it that there is an epiphyllum fairy who is very beautiful and blooms brilliantly every day. At that time, a young man named Wei Tuo watered her every day. Day after day, Epiphyllum fell in love with Wei Tuo. But it didn't last long. The jade emperor was furious when he learned that, and separated them. He turned the epiphyllum fairy into an epiphyllum that can only bloom once a year, removed Wei Tuo's memory and sent it to Ling jiusan to become a monk.

? Fairy Epiphyllum still can't forget Wei Tuo. She knew that he would go down the mountain to collect tea for the Buddha every spring, so she gathered all her energy and opened it when Wei Tuo went down the mountain. She hoped that Wei Tuo would think of herself when she saw the blooming epiphyllum. But Wei Tuo has long forgotten the past. Even though Epiphyllum bloomed around Wei Tuo year after year, Wei Tuo never remembered her.

? This story is a very romantic love story, and a short-lived one is obviously about the persistence and beauty of love. Epiphyllum God is extremely persistent in love. Even if she is punished, even if the other person doesn't remember herself for a long time, she still blooms year after year in the place where Wei Tuo passes, just to arouse his memory and pursue the yearning love. However, in our opinion, a flash in the pan generally means that what is popular is only temporary and will soon die out.
