Overview
The twenty-sixth of the Thirty-six Lesser Grotto-Heavens, titled the “Heaven of Great Yu's Flourishing Wonder,” governed by the Perfected Yin. Identified with present-day Mount Dayou in Yuanling, Hunan, known together with Mount Xiaoyou as the “Two Yous”; the saying “learning enough to fill five cartloads, books enough to rival the Two Yous” derives from this site, which has the Eryou Caves and a Book-Hoard Cave.
