《太平广记·卷四十四·神仙四十四》
萧洞玄于是周游天下，经过五岳四渎，名山异境，都城村落，凡是人迹所聚集的地方，没有不到的。经过十多年，仍然没有得到那个志同道合的人。
盍求诸乎？ 洞玄遂周游天下，历五岳四渎，名山异境，都城聚落，人迹所辏，罔不毕至，经十余年，不得其人。
Xiao Dongxuan, therefore, travelled around the world, passing through the Five Sacred Mountains, Four Famous Rivers, famous mountains and different places, capital cities, villages, and wherever people gathered. He had not missed any places. After more than ten years, he had still not found that like-minded person.
