From Industrial Wastewater Discharge Site to Wetland Park with Birds and Flowers

There is a large enterprise in Fangshan District of Beijing, Yanshan Petrochemical Company.

Our staff members told us that smelling something tasty is not terrible. The most terrible thing is the erosion of people by odorless poisonous gases.
