Guangzhou's Lianhuashan Port is strategically located at the Lingding Ocean estuary, with direct waterways leading to Hong Kong and Macao. The operation mode realizes "one declaration, one inspection and one release" of import and export goods, streamlining the procedures at coastal ports.

Guangzhou Customs and Guangzhou Port have innovatively launched the "One Port in the Bay Area" reform, with Nansha Port as the hub port and the Pearl River inland ports as feeder ports.
