Hallo can you please let me know how to Get from yiwu AirPort to international trade City.

From the airport, the local public bus Y102 can take you to reach the international trade city directly. This bus stops many stations before reaching the terminal. The bus from the city operates around from 06:50 to 17:50.
Or you can take the bus line 800 to reach Ocean Hotel and then take a taxi to reach the trade city. The bus only stops twice before reaching the terminal. But I am not very clear about the bus operation time.
