Literature Reference: By the banks of the Jiang and Han rivers, the king commanded Shao Hu: 'Expand the four directions, secure our land. Without distress or urgency, the kingdom reaches its zenith. From border to border, to the South Sea, manage and govern.' The king commanded Shao Hu: 'Spread the word far and wide. Receive the mandate from the civil and military, Shao Gong is the pillar. Do not say I am young, Shao Gong is a model. Initiate diligently in military affairs, thus I bestow upon you blessings.' Source from 'The Book of Songs·Da Ya·Dang Zhi Shi·Jiang Han'.
