Introduction to Jianshan Building: This building is surrounded by water on three sides and mountains on two sides. It is a Jiangnan-style residential building. The ground floor is called the "Lotus Champs". There is a King Wu's chair on the outer corridor along the water. When taking a rest, you can watch the fish up close and appreciate the lotus flowers in the middle. From a distance, the scenery in the garden slowly unfolds before your eyes like a painting. The upper floor is the Jianshan Tower, which is taken from Tao Yuanming's famous saying: "Pick chrysanthemums under the east fence, and leisurely see the Nanshan Mountain." From the upper floor, you can have a panoramic view of the beautiful scenery of the Central Garden.
