Why can't I get into Shikou Town Chemical Industry Park in Dongying City?

Dongying Shikou Town Chemical Industry Park cannot enter because of regulations. Dongying Shikou Town Chemical Industry Park strengthens the management of enterprises, transport units and their key vehicles and employees in the park, and strictly implements the "instant messaging" filing of freight vehicles. No foreign freight vehicles without filing are allowed to enter the enterprise. So you can't go in there.
