Why did the Shang Dynasty move its capital many times?

The Shang Dynasty frequently moved the capital for the following reasons:

1. The Yellow River often floods and destroys the old capital;

2. Shang Dynasty advocated divination and moved the capital because of divination;

3, agriculture is backward, and after a period of time, the land fertility is exhausted and the capital has to be moved;

Due to the serious political struggle between nobles for the throne, the new king often moved the capital after he succeeded to the throne.
