《资治通鉴·汉纪·汉纪三十五》
邻县曾有人报私仇，官民震惊，传言羌人反叛，百姓跑到城内。狄道县长上门，请求关闭城门征调军队。
傍县尝有报雠者，吏民惊言羌反，百姓奔入城，狄道长诣门，请闭城发兵。
There was once a personal revenge plot in a neighboring county, and because of this, the officials and civilians were frightened and said there was a Qiang rebellion, and the people ran into the city. The county head of Didao went to Ma Yuan's house and asked for the city gates to be shut and for troops to be ordered out.
