《资治通鉴·唐纪·唐纪四十三》
卢杞召来大理正田晋，商议处罚二人的刑律依据，田晋认为： 根据刑律，本人管理官府设立的市场，购买物品获取余利的，以索取论处，应当剥夺官位。 
杞召大理正田晋议法，晋以为： 律，监临官市买有羡利，以乞取论，当夺官。 
Lu Qi summoned Zheng Tian, the official in charge of Dali Temple, to discuss the legal basis for punishing the two. Zheng Tian believed that according to criminal law, those who manage markets established by government agencies and purchase goods to obtain profit should be punished for extortion and deprived of their official positions.
