Introduction to Youyou Pavilion: At the beginning of the Ming Dynasty in the Northern Song Dynasty, Shen Miao, then a marquis, liked to climb mountains in his free time. He got a platform in Wushan and nominated it as "Junqing Terrace". Ten years later, he was invited by the monks of Sakyamuni. The platform was used as a pavilion, with the "secluded" artistic conception nominated, and Cai Xiang, one of the four great calligraphers of the Song Dynasty, was invited to write poems to record the pavilion.
