Brief Introduction of the Seires
Hetao is a region on the upper reaches of the Yellow River in Northwestern China. The Yellow River, when it reaches Inner Mongolia, finds its way blocked by the Helan Mountains. So, the river turns northward. Two other ranges, the Yin Mountains and the Taihang Mountains, force the river to make two further major changes of course. The result – evident if you look at a map – is that the Yellow River describes the shape of a gigantic tree stump. The area of land that lies within this tree stump is called Hetao, which literally means "bend " or "meander".
