After Liu Yi surrendered, he followed orders and returned to Bingzhou with the remaining clansmen. To prevent the Xiongnu soldiers from gathering and causing chaos, Zhao Hanzhang only released some veteran soldiers and wounded soldiers, while the rest were dispersed. She selected Xiongnu leaders to take them to Bingzhou for field cultivation, road construction, and canal digging.
After the Xiongnu occupied the Hexi Corridor, they drove the Han people to farm the land and enclosed areas for grazing. Few of them knew how to cultivate.
Recognizing their lack of expertise, Zhao Hanzhang allocated several areas for them when sending them back to Bingzhou, consisting of half farmland and half pasture.
She allocated the fields and grasslands to each household, allowing them to graze and plant crops. She even dispatched many people from the Ministry of Agriculture to guide them in farming.
