Xu Changan, a graduate student in the Department of History, transformed into a runaway boy in the first year of Wude, and gained an immortal body for nothing. He did not dare to be a god, so he only set up a cake stall in the West Market of Chang'an. King Qin's soldiers came to buy cakes, Wei Zheng paid for them on credit, and Li Bai wrote poems about Hu cakes. He also served in court and as an official, and was hunted down by an organization called "Wangxianlou" for half of the history of the Tang Dynasty; he loved several girls and sent them away one after another. From Wude to Tianyou, the city of Chang'an has aged one generation after another. He is the only one standing at the entrance of Xishichi, leaving a mouthful of warm food for those who cannot come back. The Tang Dynasty died, but his cake was still hot.
