The legend of lucky grass
A long time ago, there was a couple who really loved each other and lived together in a beautiful peach grove, but because of a small thing, they couldn't agree. Finally, one day, Cupid couldn't take it anymore. She floated to the peach grove where they lived and quietly told a lie: tell them that all parties will be in trouble, and only by finding the four-leaf clover in the deepest part of the peach grove can they be saved.
After listening to their words, I pretended to be indifferent, but I was still worried about each other. It was raining that night, and it was a rainstorm, but they secretly went to the deepest part of Taolin to find a four-leaf clover for each other. When they knew that the other person cared about themselves, they were moved and decided to let the four-leaf clover witness their love. Cupid smiled.
This is Cupid's joke, because she doesn't want happiness to come too easily. Only those who care and cherish each other deserve happiness. So the four-leaf clover is the witness of love.
