Introduction to the Bupee Garden: The small island in the center of the lake is the "Bupee Garden", which is an ingenious small garden modeled on Suzhou gardens. Dong Zhongshu studied hard and did not go to his back garden for three years, leaving behind the allusion of "the eyes cannot see the garden". There are three buildings on the island - "Xueer", "Shensi" and "Yixing".
