《资治通鉴·唐纪·唐纪六十五》
李承勋认为说得有理，即向唐宣宗上奏，请求任命尚延心为河、谓两州都游弈使，让他统率其部众居住于这两州地方。
承勋以为然，即奏延心为河、渭都游奕使，使统其众居之。
Li Chengxun thought it made sense, and immediately submitted a memorial to Emperor Xuanzong of Tang, requesting the appointment of Shang Yanxin as the governor of He and Wei, and let him lead his tribe to live in these two states.
