《旧唐书·列传·卷二十二》
而记载评述的人，多守常规，在感情上没有不忘记古今的差异，在道理上不明白治世乱世的风气厚薄不同，欲在百王的末世，实行夏商周的治国办法。
而著述之家，多守常辙，莫不情亡今古，理蔽浇淳，欲以百王之季，行三代之法。
However, the people who recorded and commented on them mostly clung to the norm, did not take into account the differences between ancient and modern times in terms of emotion, and did not understand the essential differences in social customs between peaceful and troubled times. They wanted to implement the governing methods of the Xia, Shang, and Zhou dynasties in the declining years of a hundred generations of kings.
