Is the program of Jincai Youth Travel Service normal?

Ordinary. The film crew of Tianjin TV Children's Channel "Jincai Youth Travel" made a special trip to Dagukou Fort Ruins Museum to visit four issues, which was very formal. Based on the precious collection of the museum and its related historical and cultural knowledge, the film crew explored the vicissitudes of Dagu area through the lens and gradually searched for the story behind the "Dagu Iron Bell", the treasure of the town hall.
