Introduction to Ermei Bookstore: There are two plum blossoms in front of it, forming a self-contained courtyard. There is a gray plastic snow cave on the east side, called the "Seven Star Cave". The third entrance is the flower hall, and all doors, windows, walls and boards are made of nanmu. The doors and windows are all double-layered, with window paper in winter and window screens in summer; the wall panels and the upper blocking panels of the door leaf all have lacquer paintings of trees, flowers, birds and dramatic stories. There are two ancient pavilions built in the small garden in front of the hall, one of which is a hexagonal half-side pavilion, with a lychee tree and a palm tree that are more than a hundred years old. Lin Huimin, an academician of the Chinese Academy of Sciences, once lived in this hospital.
