A literati scholar of substantial classical learning (deep in jīngshù 經術), with a particular interest in astronomy, calendrical reckoning, and natural history, alongside active rural medical practice — he attended even the poorest patients in person and was regarded as a “living Buddha” (shēngfó) by his contemporaries.
