What advice did Emperor Wen of Han adopt to issue imperial edicts to raise people's disciples under the fortress?

Who do you want to ask is whose suggestion was adopted by Emperor Wendi of Han Dynasty to raise people to emigrate to Xiaxia? Chao Cuo. According to the information on the website of Tuhua Education, in the first 1 1 year (BC 169) before Wendi ascended the throne, Wendi adopted Chao Cuo's suggestion and sent a letter to recruit a large number of people to move and live in the frontier areas of Xiasai. Chao Cuo, a native of Yingchuan (now Yuzhou, Henan), was a statesman and writer in the Western Han Dynasty. Facing the problem of how to resist the invasion of Xiongnu, Chao Cuo put forward the strategic concept of "migrating to the real frontier" to Emperor Wen of Han Dynasty, and suggested that the people should be nurtured to enrich the frontier fortress and actively prepare for the invasion and plunder of Xiongnu.
