Description：Niu Dabao (played by Bao Beier) wholeheartedly likes a woman named Yuan Yu'e (played by Wang Ou) and launches a passionate offensive against her. Unexpectedly, he becomes a member of Huanghua Station, the main post station in the capital, by mistake. Later, Niu Dabao is shocked to find that Yuan Yu'e is a member of the Hong Gang, which is one of the anti-Qing gangs that Huanghua Station vigorously suppresses and clears. Although Niu Dabao is not good-looking, he has extraordinary wisdom. On the surface, he is loyal to Huanghua Station and has gained the trust of the station chief Long Dinghai (played by Lin Xue). On the other hand, he repeatedly lends a helping hand to Yuan Yu'e when she is in distress, and therefore gets acquainted with Chunhua (played by Jia Ling) and Tie Qianding and other capable people. Niu Dabao discovers that a sinister conspiracy is brewing in Huanghua Station. Can he, with his courage and wisdom, crack this conspiracy and protect the people?
