Fei Longding

• Fei Longding (費龍丁) was from Songjiang County (now part of Shanghai). Later, he changed his name to Yan (硯), with the courtesy name Jianshi (見石), and adopted Longding (龍丁) as his pseudonym. In his later years, he embraced both Buddhism and Christianity, which led him to adopt the title Buddha-Christian Layman (佛耶居士).
