《太平广记·卷二·神仙二》
甘需说： 西王母所设的酒宴，不是人世间的东西，那些玉酒金液，都是需要万年的时间酿制用来供神仙享用的，燕昭王既然吃了，自然就得道了，只要虚心高洁的静修，自然会保持长生的。 
甘需白： 王母所设之馔，非人世所有，玉酒金醴，后期万祀，王既尝之，自当得道矣。但在虚疑纯白。保其遐龄耳。 
Gan Xu said: The Queen Mother of the West did not prepare her banquet with worldly foods. The jade wine and golden liquid all take ten thousand years to ferment, and are used by the immortals as offerings. Since King Yan Zhao ate them, he must have obtained the Way. As long as he cultivates with a pure and humble heart, he will naturally remain immortal.
