《资治通鉴·汉纪·汉纪四十三》
如果真正愿意头枕山峰，身卧山谷，步巢父、许由的后尘，那就罢了。如果认为应该出来辅佐朝廷，拯救百姓，现在正是时候。
诚遂欲枕山栖谷，拟迹巢、由，斯则可矣；若当辅政济民，今其时也。
If you truly wish to rest your head on a mountain peak, lie down in a mountain valley, follow the steps of Chao Fu and Xu You, forget it. If you believe you should come out and assist the court, save the people, now is the time.
