During the Eastern Jin 東晉, discussing philosophy and preaching Buddhism became fashionable among the gentry. The gentry were introduced and converted to Buddhist doctrine by many kinds of occasions and activities, such as hypothetical discourses, debates, public sermons and social gatherings. After the course of several hundred years, the gentry accepted Buddhism with literati and eminent monks keeping good company, as recorded in various works. For intance, Shishuo xinyu世說新語is a work that collected mainly the ideology, words and deeds of literati, but also included some records of emiment monks. On the other hand, Biography of Esteemed Monks高僧傳primarily recorded the beliefs, thoughts and actions of eminent monks, yet included some records of some literati. The fact that both literati and eminent monks concurrently appeared and acted spiritedly in medieval Chinese's cultural circles circles could imply that one other kind of scholar exists in between these two: the lay Buddhist. Xie Fu 謝敷, being neither a famous literati nor an eminent monk in Eastern Jin, was often called a "lay Buddhist"居士. Despite the paucity of ocumentation on Xie Fu, this article attempts to conduct research on him by collecting materials on him from works such as the Shishuo xinyu, Biography of Esteemed Monks, Jin shu 晉書, Chu sancang jiji 出三藏記集, Guanghong mingji 廣弘明集, Guan Shiyi yingyan ji 觀世音應驗記 and Mingxiang ji 冥祥記. This article will describe more clearly Xie Fu's family background, life, social intercourse and beliefs. In addition, and outline will be made of the form, beliefs and ideology of a typical lay Buddhist of that time and an investigation made into such a lifestyle in the context of converging Confucian and Buddhism doctrines.
