《太平广记·卷六·神仙六》
这个国里的人都用珍珠白玉串成席子，他们让我进入云霞作成的帐幕里，让我躺在墨玉雕成的枕头上，枕头上刻着日月云雷的图案，这种枕头叫 镂空枕 ，也叫 玄雕枕 。
其国人皆织珠玉为簟，要臣入云韍之幕，设玄珉雕枕，刻镂为日月云雷之状，亦曰 镂空枕 ，亦曰 玄雕枕 。
The people in this country use pearls and white jade to make mats, let me enter the cloud tent and make me lie on a pillow made of glazed jade, and the pillow is engraved with the pattern of the sun, moon, clouds and thunder. This pillow is called "hollow pillow", also called "Xuandiao pillow".
