Zhang Yiheng had a long dream. After a while, a girl with two pigtails appeared in the dream and said to him: "Yiheng, I want to eat that marshmallow." After a while, the girl in the dream turned into short hair and said to him: "Yiheng, I finally got my salary, and I bought you a SNOOPY pen. HELLO KITTY's note, don't call me naive, use it!" After a while, the girl in the dream had tears on her face and said to him: "Yiheng, you actually did such a thing, I'm leaving, and I will never see you again!"
