I visited the Xiaoling Tomb of the Ming Dynasty with a friend before. When we started chatting, I told my friend that I could write a story about the Xiaoling Tomb of the Ming Dynasty. The hero would be called "Xiaoling Tomb of the Ming Dynasty". A friend was taking pictures of the Catalpa tree in Xiaoling Mausoleum of the Ming Dynasty and said that the heroine could be called "Calpa".
This is the original origin of this story.
"I like to be good at math."
"What a coincidence. I've always been good at math."
Intention: I hope that when you accidentally think of me in the future, you will feel more joy than sadness.
