《旧唐书·列传·卷三十六》
王若暗中去东都洛阳，如从天而降，派人杀掉留守，就领兵西据陕州，东下黄河，这样天下可图。 
王若潜行直诣洛阳，亦是从天上落，遣人袭杀留守，即拥兵西据陕州，东下河北，此天下可图也。 
If Wang Ruo goes to Luoyang, the capital of the east, secretly, coming down from heaven, sending people to kill the defender, then leading soldiers to occupy Shaanxi to the west, and heading to Huanghe to the east, the world can be taken.
