Not on the overpass, but on the small bridge west of Tangshan Old Water Company and Pipe Factory, pigeons are bought and sold every Friday.
The location is 100 meters east of the intersection of Wenbei Road and Jilaishui Street.
You can take the bus as long as it goes to Tangshan East Station. Get off at the East Station and walk west (there is only one road with no intersection). It is about 1000 meters away. When you pass the entrance of the water company, you will see many people buying and selling pigeons.
, it is recommended that you first check the Tangshan City map online to understand the terrain.
