《太平广记·卷四·神仙四》
后来有一次武帝到华林苑狩猎，用弓箭射虎和犀牛，弓弦突然断了，王母的使者正好在武帝身帝随侍，就对武帝说： 请您拿一分王母献来的灵胶，用嘴把胶浸湿后，就可以把断了的弓弦接好。 
帝幸华林苑，射虎兕，弩弦断。使者时随驾，因上言，请以胶一分，以口濡其胶，以续弩弦。
Later, once Emperor Wu went to Hualin Park for hunting and shot tigers and rhinoceros with a bow and arrow. The bowstring suddenly snapped. The Queen Mother's emissary was serving Emperor Wu, and he said: Please take some of the fairy glue from the Queen Mother and moisten it with your mouth. After that, the broken bowstring can be glued back.
