Before Prince Dai left the Northern Border, Prince Han made a special trip from Youzhou to bid him farewell, gifting him with numerous items. Before the soldiers and officials stationed at the Northern Border, Prince Dai and Prince Han put on an act of deep brotherly affection, leading the common people to believe their rapport was genuinely strong.
Chu Ying did not return to the capital with Prince Dai; he stayed at the Northern Border. When the emperor issued the decree for Prince Dai to return to the capital, he also gave Chu Ying an imperial decree, appointing him as the Great General of the Northern Border Camp, tasked with continuing the defense against the Xiongnu.
Prince Han did not anticipate that the emperor would retain Chu Ying. Logically, the emperor was supposed to call him back to the capital, especially given that General Deng had already recovered.
