In which city was the front end taken?

The title of this play should be the beginning, which was shot in Xiamen.

The original scene of the police station was actually built in the studio of Xiamen Film and Television Shooting Base. The shooting base will be put into use at the end of 2020. According to the relevant personage of Xiamen Film and Television Industry Service Center, during the filming of Heart in Xiamen, the center also provided comprehensive coordination services including co-production service, studio service and commissioned production service.

The play begins with Haicang Bridge, which is the second largest three-span fully floating steel box girder suspension bridge in the world and the first in Asia. Haicang Bridge is also an "old actor" in major TV dramas. It is not uncommon for a bridge to become a scenic spot, but it can become a tourist area, a national 4A level, and even a museum has been built for it. This is the characteristic of Xiamen.
