Simply put, the Wulong River is a tributary of the Minjiang River, surrounding the southern part of Nantai Island. The Minjiang River originated in Shang Jie, with Bailong River as its north tributary and Wulong River as its south tributary. When it reached Mawei in the south of the canyon, two rivers merged into the sea.
Let me give you a brief introduction of these two rivers, hoping to help you understand their relationship further.
Minjiang River, the largest river that flows into the sea (East China Sea) alone in Fujian Province, China. Originated in Junkou Town, Jianning County at the junction of Fujian and Jiangxi. Jianxi, Futunxi and Shaxi, three main tributaries, are called Minjiang River after they meet near Nanping City. Crossing the coastal mountains to Nantai Island in Fuzhou, it is divided into two branches, north and south, and merged with Luoxing Tower, and then flowed out of Langqi Island to the northeast and flowed into the East China Sea. Shaxi is the main source, with a total length of 562 kilometers and a drainage area of 60,992 square kilometers, accounting for about half of the total area of Fujian.
After the Minjiang River flows to Huai 'an, Fuzhou, it is divided into two tributaries, Bailong River and Wulong River, and the two tributaries meet to form Majiang River into the sea. Located on the south side of Nantai Island, Wulong River flows into Majiang via Huai 'an, Tang Hong, Fenggang, Yang Qi, Luozhou and Xiamen.
