《宋书·列传·卷六十二》
羊欣一向喜欢黄老之学，常常亲手抄写这类书籍上的章节。他有病不吃药，只喝符水而已。
素好黄老，常手自书章，有病不服药，饮符水而已。
Yang Xin has always loved the study of the Yellow Emperor and the Old Man, and often personally copied chapters from books on these subjects. When he was ill, he refrained from taking medicine and only drank talisman water.
