In Yiwu:

The main stream of Dongyang River entered the county from the southeast of Hezhai in Lisan Township, and was named Wushanghe, Yiwu River and Dongjiang River successively. The water flow in dry season is not large, but it increases greatly in flood season. Because the upstream slope is steep and the downstream flow is steady, floods often occur before the founding of the People's Republic of China, and the riverbed swings from north to south. Farmers along the river regard it as a "rotten belly", and there is an agricultural proverb of "ten years south of the Yangtze River and ten years north of the Yangtze River". In the summer of 1922 (1 1 June, 2002), the flood of Dongyang River soared, and the bend of Dongjiang levee in Hu Mei Village of Dongqiao Township was washed away.
