《隋书·列传·卷三十二》
曹旦等人听从了他们的劝告，于是就让裴矩把八枚传国玉玺，给魏征和李公淹，将崤山以东的土地全部归顺到大唐。
旦等从之，乃令矩与徵、公淹领旦及八玺，举山东之地归于大唐。
Cao Dan and others listened to their advice, so he let Pei Ji take the eight Chuan Guo Jade Seals to Wei Zheng and Li Gonyan, so that all the land east of the Xiaoshan Mountains would be subject to the Tang Dynasty.
