译文如下：
仙翁归卧翠微岑，
One immortal is resting on the green hill slope,
一夜西风月峡深。
In the deep night, Western wind blows and moon shines.
松径定知芳草合，
The path of pine trees certainly knows when fragrant grasses will grow,
玉书应念素尘侵。
A jade book will surely remember the intrusion of plain dust.
闲云不系东西影，
The idle clouds are not bound by East and West,
野鹤宁知去住心。
Wild cranes do not know the concept of staying or leaving.
兰浦苍苍春欲暮，
The Lanpu is green and green, and spring is about to pass,
落花流水怨离琴。
Falling flowers and flowing waters lament the departing qin (a musical instrument).

此诗以山水为背景，展示了仙境之美。作者通过描绘仙山的景色和气氛，表达了对仙境的向往和渴望。仙山的山色青翠、环境幽雅，一夜之间风华骤起，仙山的西风赋予了月峡深远的诗意。
