Literature Reference: If Yi, from 'The Book of Songs·Da Ya·King Wen': 'King Wen is above, shining in the heavens. Though Zhou is an old state, its destiny is renewed. The mandate comes from heaven, appointing King Wen. In Zhou and its capital, the daughter of the noble family bears a son, King Wu. Protected and commanded by heaven, he leads the campaign against the great Shang. The armies of Shang are like a forest. Arrows fly in the wilderness, and I rise as a lord. God watches over you, do not waver in your heart.'
