Detailed explanation-1: -The river is often called “China’s sorrow” because millions of people have been killed by flooding. The worst flood disaster in world history occurred in August, 1931 along the Huang He River in China and killed an estimated 3.7 million people.

Detailed explanation-2: -The river takes its name from the large amounts of fine yellow sediment (loess) colouring its water. The extensive silt deposition in the river’s lower reaches across the North China Plain and the expansive stretches of flat land surrounding it have always made the area extremely prone to flooding.
