An account of Jiang Ziya's life written long after his time says he held that a country could become powerful only when the people prospered. If the officials enriched themselves while the people remained poor, the ruler would not last long. The major principle in ruling a country should be to love the people; and to love the people meant to reduce taxes and corvée labour. By following these ideas, King Wen is said to have made the Zhou state prosper very rapidly.
