《明史·列传·卷二百一十五》
刘瑾掌权，全用宦官充当监军，杨一清感到没有职权，便挂职而去，这样文贵、才宽二人相继被委以该地区事务。
刘瑾用事，监军皆阉人，一清不得职去，文贵、才宽相继受事。
When Liu Jin was in power, he used eunuchs as military supervisors, which made Yang Yiching feel powerless and leave his post. Consequently, Wen Gui and Cai Kuan were appointed as general managers of the area one after another.
