In the 1940s, Shanghai was not at peace, and many strange cases occurred.
Gongsun Che, the detective of the Investigation Department of Shanghai No. 1 Police Station, has an eccentric, playful and intelligent nature. He can often come up with all kinds of strange tricks to turn dangerous things out of danger and make difficult cases simple. He also angered the six deputy detectives who worked with him because of his young nature, until the appearance of deputy detective An Chen.
An Chen is a detective from a police station in the suburbs of Shanghai. Due to his work, he was transferred from the police force to work with Gongsun Che. An Chen is old-fashioned and conservative but has a sense of humor. His personality is incompatible with Gongsun Che, but he talks to him about everything in private. In the end, they are friends for life and death.
Because the two had very different ideas for handling cases, Liu Haoxin, the only detective in the department, was often sent to do dangerous things. Gongsun Che also made fun of him in various names, and was "molested" by An Chen.
Because of the appearance of An Chen, the entire investigation department was greatly changed, and together with Gongsun Che and Liu Haoxin, they called themselves the "threesome"
While solving various cases, I also gained my own love.
