《资治通鉴·唐纪·唐纪六十二》
我认为，朝廷应当派遣使者前往安抚他们，运送粮食赈济他们，这也就是当年汉宣帝之所以能臣服匈奴呼韩邪单于的策略。 
宜遣使者镇抚，运粮食以赐之，此汉宣帝所以服呼韩邪也。 
"I believe the court should arrange for an emissary to visit and comfort them while transporting food to provide relief. This is the same strategy that Emperor Xuan of Han used to bring the Xiongnu Huhanye Chanyu under submission."
