Ding Liao is a new choreographer and director of the wide-angle Jiangxia column, living with his younger brother Ding Man. On this day, uncle's friend Jiang Kan, a doctor of pharmacy, is going to move in temporarily. According to his WeChat account, the two suggested that the other party should be an old-fashioned middle-aged man. When they arrived at the airport to pick up the plane, they mistakenly identified the middle-aged passenger Mr. Jiang. As Jiang Kan, it was not until Jiang Kan recognized Ding that he realized that he had made a mistake. The next day, I went out to a university and came across Jiang Kan on the way. When he was leading the lecture materials, Jiang Kan's colleague Juzi recognized it, and the two complained about the "Demon King" Jiang Kan together, but they were accidentally heard by Jiang Kan. At the beginning of the lecture, Hu Jiaying told that today's lecturer has a particularly powerful and proud student, and he is very handsome, so he didn't care about it. Until the professor introduced Jiang Kan to the stage, it was unexpectedly discovered that the young and promising student of the professor was actually Jiang Kan.
