《旧唐书·列传·卷十九》
臣现在所以陈述见闻，并不敢偏爱君集等，希望用萤火蜡炬般微弱的光，增添日月的光辉。
臣今所以陈闻，非敢私君集等，庶以萤爝末光，增晖日月。
What I have now set forth are my humble observations, not because I am partial to Junji and the others, but rather in the hope that my light may add to the brilliance of the sun and moon like the glow of a firefly or a torch.
