The yellow river (huang he river) does not contain as many cities along its banks as other rivers in china. why is this the case?

Here is the reason why the Yellow River or Huang He River does not contain as many cities along its banks as other rivers in China. The reason why is that, the river erodes the loess easily, carrying along sixty times the sediment load. During floods, the river bursts its banks which turns the plain into a flood plain. This place has become more dangerous as China's population increases. Hope this helps.

City because the country has land and not that many things that can get damaged.
