I Tell Stories in the World of Yin and Yang

My grandfather is a coffin seller, and he often does some feudal and superstitious things for people. Grandpa likes to have a few drinks every day, and every time he drinks, he will brag to me. It is said that I was born in a yin year on a yin day and a yin time. As soon as I landed on the ground, there was a gust of wind and hundreds of ghosts walking at night, seeking my life. He also said that when I was born, one of my three souls and seven souls was missing. I wear a piece of old jade in the shape of a copper coin that is crystal clear and has a hint of red in the middle. Grandpa told me that I cannot take it off no matter what. It took a lot of work to save my life. If I took it off, I would die. Grandpa also said that my destiny was to enter the underworld. There is a big disaster at the age of 20. I have always regarded what my grandfather said as drunken nonsense. Because I never believed it. Until I was 10 years old. Something happened that broke my concept of feudal superstition.
