《旧唐书·列传·卷一百二十四》
到他做官担任藩镇，出将入相，三十年间未再重游，但他所题写的文字诗章，全部刻在这座别墅的石上。
及从官籓服，出将入相，三十年不复重游，而题寄歌诗，皆铭之于石。
When he became an official, a藩镇, a military governor or a prime minister, and in the past thirty years he never came back, but he wrote and engraved all of his poems and essays onto the stone in the villa.
