The paper sums up the basic status of clergyman's poetry in this period, and makes a specific research on the scattering situation, collection of scattered writings and textual criticism of certain collected works. The ignorance of clergyman's poetry leads to the serious loss of documents; vise versa, the loss of documents directly results in the neglect of clergyman's poetry.
