《资治通鉴·唐纪·唐纪四十七》
由于泾州临近边疆，镇兵屡次杀害军中主帅，经常成为祸乱的根子，于是李晟上奏请求前往处治不肯听从命令的人们，让他们努力种田，积聚粮食，以便打击吐蕃。
李晟以泾州倚边，屡害军帅，常为乱根，奏请往理不用命者，力田积粟以攘吐蕃。
Since Jingzhou was near the border, the garrison troops had killed their commanding officers many times, and often became the root of trouble, so Li Sheng requested to be sent there to punish those who would not follow orders, to make them work hard on the land and stockpile grain to strike at the Tufan.
