《太平广记·卷一百三十六·征应二》
药还没有熬好，就觉得有些疲累，就闭着眼睛休息一会，忽然就象有神灵感应似的，抬头一看，有个神仙有一丈多高，还有一匹装饰齐备的马。这个神仙身披金甲，手拿长戈，围着煎药的锅转了三圈，然后把煮的药全都给倒了。
肸蚃之际，有神人长丈余，马具饰，身被金甲，操戈，绕药鼎三匝，煮尽覆无余焉。
The medicine had not yet been boiled well, when he felt somewhat tired, so he closed his eyes to rest for a while. Suddenly, as if from a divine spirit, he looked up and saw a god over ten feet tall, and a well-decorated horse. The god was wearing golden armor, holding a long halberd, and circled the pot where the medicine was being boiled three times, and then poured out all the medicine that had been boiled.
