Where is the largest tributary of Qiantang River?

Qiantang River, called Zhejiang in ancient times, is also called Zhejiang, Zhijiang and Luosha River. Generally, the Fuyang section of Zhejiang Province is called Fuchun River, and the Hangzhou section of the lower reaches of Zhejiang Province is called Qiantang River. . The Qiantang River was first named after Shan Hai Jing and the ancient Qiantang County (now Hangzhou)? , is one of the main cradles of Wuyue culture.

In 1980s, Zhejiang Province organized a scientific investigation team to make an in-depth on-the-spot investigation on Xin 'anjiang River, and determined that Qiantang River was Xin 'anjiang River, and its source was located at Liugujian, the main peak of Huaiyu Mountain at an altitude of more than l600 meters in Xiuning County, Anhui Province. The estuary is located on the line from Ganpu, Haiyan County, Zhejiang Province to Xisanzha, Yuyao City on the other side, with a total length of 605 kilometers.

The main tributaries of Qiantang River are Xiuning River, Qiayang River, Guixi River, Lianjiang River, Changxi River, Shouchang River, Lanjiang River-Qujiang River-Changshan Port-Ma Jinxi River, Jinhua River-Dongyang River, Zhuqing Port, Fenshui River, Dayuanxi River, Luzhu River, Huyuanxi River, Puyang River and Caoejiang River. The larger rivers are Lanjiang, Wujiang, Fenshui, Puyang, Caoejiang and Luzhu.

The largest tributary of Qiantang River is Lanjiang River, which is regarded as the main source of Qiantang River in history because of its wide channel, and has become the dividing line between East Zhejiang and West Zhejiang. After the founding of the People's Republic of China, the length of Xin 'an River was measured, and it was found that Xin 'an River was longer than Lanjiang River. Because Xin 'an River is winding and narrow, it is not regarded as the positive source of Qiantang River. The source of this river is only a long way. After the renovation of Xin 'anjiang River, Lanjiang River can only be the largest tributary of Qiantang River.
