《太平广记·卷九·神仙九》
我曾听前辈说当年有个吕恭带一仆一婢进太行山采药，再也没回来，可能是让虎狼吃掉了，至今已二百多年。
吾昔闻先人说云，昔有吕恭者，持奴婢入太行山采药，遂不复还，以为虎狼所食，已二百余年矣。
I once heard from my seniors that many years ago, there was a Lü Gong who took a servant and a maid into Taihang Mountain to gather medicinal herbs, and they never came back. They were probably eaten by tigers or wolves. It has been more than two hundred years now.
