Longhai

Longhai is a county-level city within the prefecture-level city of Zhangzhou, in the south of Fujian province, People's Republic of China. Longhai comprises territory on both banks of the lower Jiulong River, although most of its area is on the right bank. The left bank yields to Xiamen before reaching the sea, the right bank becomes the south shore of Xiamen Bay and is home to the Zhangzhou Port tariff-free industrial export zone, in Longhai's Gangwei Town. Following the revocation of the sea ban in the late Ming, Yuegang became a key port for China's silver trade with Manila in the Spanish Philippines. It was one of Fujian's four main commercial ports, located within presentday Haicheng in Longhai.
