Why did the early Chinese settle in yellow river valley and the Yangtze river valley?

The civilization was developed near the yellow and yangtze river because For thousands of years, the river has been known as the mother river of the Chinese nation, both in the writings of the poets and scribes, and in the hearts of the Chinese people. Almost all the Chinese see themselves as the children of Yellow River. It is said that Egypt is the gift vouchsafed by the Nile. If there were no Nile, then it is hard to see how there could be an Egyptian civilization. The Yellow River has the same relationship with China. If China had no Yellow River, the Chinese wouldn't have a place to focus their spiritual energies on. Yellow River drainage basin is the birthplace of Chinese nation and meanwhile it is the cradle of Chinese civilization. In this vast cradle, Yellow River civilization, which is the principal part of the whole Chinese civilization and plays a crucial role in the history of civilization development, grew with vitality. It had stood the test of almost all kinds of upheavals and difficulties, and finally created the continuous Chinese civilization.
