Answer for number one: The early leaders of the Zhou Dynasty introduced the idea of the "Mandate of Heaven". The government of the Zhou was based on the feudal system. The emperor divided the land into fiefs that were usually ruled by his relatives. The nobles who ruled the fiefs basically owned the farmers who worked their lands.

Answer for number two: The North China Plain extends over much of Henan, Hebei, and Shandong provinces, and merges with the Yangtze Delta in northern Jiangsu and Anhui provinces. The Yellow River meanders over the fertile, densely populated plain emptying into the Bohai Sea.
