Liu Che, Emperor Wu of the Han Dynasty, ascended the throne at the age of sixteen. He denounced Fang Qiu, attacked the Xiongnu in the north, and conquered Baiyue in the south. His merits and demerits in his life are open to comment. When he opened his eyes again, he was lying on a cold hospital bed. A man in strange clothes (white coat) was shining a small flashlight into his eyes. "Don't worry, I have a slight concussion and it won't affect the afternoon shooting." "I just got too involved in the drama, and I really thought I was Emperor Wu of the Han Dynasty." Liu Che: "?" Where is my Jianzhang Palace? Where is my Wei Qing and Huo Qubing? Also, that grassroots team called "the crew" dare to make irresponsible remarks about your Majesty? ! Later he learned that he had traveled a thousand years into the future and became an 18th-rate actor named Li Che. His only resource was to play... The young Emperor Wu of Han in a big-budget historical drama. Being penniless and without any relatives, if you don't perform, you will starve to death. Liu Che: OK, I'll bear with you. After the shooting started, the director looked at the picture on the monitor and smacked his thigh with excitement: "This look! The young emperor's high-spiritedness and imperial domineering heart are brought to life! This manner! Such line skills! This young man is a genius!" The assistant director beeped in a low voice: "But I heard that his poor acting skills before made people and gods angry..." The crew discovered that there seemed to be something wrong with the actor named Li Che. He always pointed out the country to the historical consultant on the set, talking about the salt and iron policy to extending the grace order, making the gray-haired old professor stunned for a while, and finally asked tremblingly: "Classmate, which school did you graduate with a Ph. D.?"
