Kao Chenghuang Song Gong tabooed Tao, and the city was born. One day, when he was lying down sick, he saw an official holding a ultimatum and leading a white horse, saying: "Please go to the exam." The official said: "Wen Zong has not come, how can I get the exam all of a sudden?" The official did not say anything, but urged him. Gong Libing went there on horseback, but the road was very unfamiliar. When you reach a city, it is like the capital of a king. When I moved to the mansion, the palace was magnificent. There are more than ten officials sitting there, but none of them know who they are, except Guan Zhuangmiao. There are two piers and two piers under the eaves.
