Introduction to Haitang Chunwu: The independent courtyard separated by the flower wall on the east side of Linglong Pavilion is Haitang Chunwu. The unique scroll-shaped brick forehead is embedded in the south wall of the courtyard. There are two crabapples in the courtyard. The courtyard paving is inlaid with blue, red and white pebbles to form a crabapple pattern, echoing the two crabapples in the courtyard. It is an ideal place for reading and leisure.
