A little girl of three or four years old stood outside the high wall of Yiwangfu, looking up at another little girl who was lying on her stomach at the top of the wall. She whispered, “Almost there! Little Baozi, come on!”,Two little girls looked exactly alike. The girl with pigtails on the wall held onto it tightly and stared at the girl with two braids below. She said in a crying voice, "Big sister, I...I'm scared...","Oh, it just jumps down as soon as I close my eyes, doesn't it"。
