《资治通鉴·后周纪·后周纪一》
刘言已到，众将便废黜马光惠，送他到南唐，推举刘言代理武平留后，上表书向南唐朝廷请求赐予旌旗符节，南唐人没有答应，便同时也向后周称臣。
既至，众废光惠，送于唐，推言权武平留后，表求旄节于唐，唐人未许。亦称籓于周。
When Liu Yan arrived, the generals abolished Ma Guanghui, sent him to Nantang, and recommended that Liu Yan act as the commander of Wuping. They submitted a memorial to the Nantang court, requesting that they be granted flags and tallies. The people of Nantang did not agree, so they also declared their allegiance to the Later Zhou.
