Legend has it that one day a boy died inexplicably in the dormitory, wearing a red vest when he died. Later, when I went to the toilet in the middle of the night, I always heard someone ask, do you want a red vest? One day, when a boy went to the toilet, he heard a man asking for a red vest all the time. He said impatiently, no, no! In the next few days, I heard someone ask, do you want a red vest? Tired of being asked, he said, that's good He was found dead the next day, wearing a red vest.
