36.104

十四年。初都人孫彥曾家世奉佛。有妾王惠稱常誦法華。忽見江浦有光。掘之得金佛一軀。光有銘曰。建武六年庚子官寺道人法新造（前稱建武者。唯晉元帝。而止及元年）。

In the fourteenth year: Earlier, Sun Yanzeng, a resident of the capital whose family had worshipped the Buddha for generations, had a concubine named Wang Huicheng who constantly recited the Lotus Sūtra. Suddenly she saw a light in the river cove. Upon digging there, they obtained a golden Buddha image. On its halo was an inscription that read: 'Made by the monk Faxin of the Official Temple in the gengzi year, the sixth year of Jianwu' (previously those that used the reign title Jianwu were only Emperor Yuan of Jin, but it lasted only one year).
