There has the second longest river in China ,it's called Yellow river .Because of the colour is yellow so called yellow river.
All of the Chinese know "25oookilometrets Long Hiking " .I also know the war between China and Janpan . The enemy force The Red Army to the yellow river .At that time the river is very hurry, and generally speaking normal people can't across.but if not forward they will died . so they decided forward , when they across the river they found they miss half people . but the main unit already alive.
The river symbol wherever Chinese want go , they can go anywhere .
