《太平广记·卷三百四十九·鬼三十》
曹唐每天都到这里游玩、赋诗。写出水底有天云漠漠，人间无路月茫茫的诗句。吟了不长时间，自认为以前写的都不如这两句。
吟之未久，自以为常制者不及此作。
CAO Tang often strolled and wrote poems here every day. He wrote the poem, “Underwater there is a boundless sky, and no road on earth under the vast moon.” After chanting for a short while, he thought to himself that the poems he had written before were all inferior to these two lines.
