I heard that King Tang of the Shang dynasty started with seventy miles of territory and eventually became the king of the world; King Wen of the Zhou dynasty only had a hundred miles of land, but he made the princes submit. Did they rely on the strength of their soldiers and generals or the multitude of people?
