Literature Reference: 江汉之浒，王命召虎：式辟四方，彻我疆土。匪疚匪棘，王国来极。于疆于理，至于南海。王命召虎：来旬来宣。文武受命，召公维翰。无曰予小子，召公是似。肇敏戎公，用锡尔祉。—— 《诗经·大雅·荡之什·江汉》 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.'
