The book Wu zhi fang (Prescriptions of Five Hemorrhoids), included in the Bibliography of the Song Annals was claimed by later scholars as a book written by Dingzhai, the lay Buddhist. Parts of its contents are cited in Wei Xian's Wei shi jia cang fang (Collections of Prescriptions of the Wei Family). By the preface of the latter book, the prescriptions of the Wu zhi fang were derived from Li Yong-he, whose son passed these prescriptions to Ma Xing-si, who, in turn, gave them to Wei Xian's father Wei Xiong-meng. Wei Xiong-meng was familiar with a calligrapher of the Southern Song Dynasty Shan Wei, nicknamed Dingzhai, the lay Buddhist, who wrote the autobiography for Wei Xiong-meng. In addition to those collected in the Wei shi jia cang fang, there are also "Li Fangyu's Prescriptions for Five Hemorrhoids Secretly Handed Down" collected in the Mi chuan wai ke fang (Prescriptions for External Diseases Secretly Handed Down) of the Ming Dynasty which are also Li Yong-he's prescriptions for hemorrhoids, outnumbering those collected by the Wei shi jia cang fang.
《宋志书目》中收录的《五痔方》一书，后世学者认为是俗家僧人丁斋所著。其部分内容被魏岘的《魏氏家藏方》引用。根据后一本书的序言，《五痔方》的药方源自李永合，李永合的儿子将这些药方传给马行思，马行思又将其传给魏岘的父亲魏雄孟。魏雄孟与南宋书法家单炜相识，单炜俗名丁斋，为魏雄孟撰写了自传。除了《魏氏家藏方》中收录的药方外，明代的《秘传外科方》中还收录了“李方隅秘传五痔方”，这些也是李永合的痔疮药方，数量比《魏氏家藏方》收录的还要多。
