Introduction to the lotus pond: The lotus pond is located in the northeast of the rockery in the southwest of the park, with the exhibition greenhouse in the north. The pool covers an area of ​​about 2,000 square meters and is full of lotus plants. There is a group of buildings with a concrete structure and pavilions on the south bank of the pool facing the water, with a total area of ​​221 square meters. The northeast part of the pond is separated into a small pond by a small curved embankment. The pond is covered with a tall and slanting sycamore tree, which has a unique scenery. There is a small stream beside the lotus pond, which twists and turns to the east. There are a few water lilies blooming sparsely in the stream. At the end of the creek is a small hill. There is a pavilion on the top of the hill, and an artificial spring flows into the stream under the pavilion. Since 1992, the creek has been filled in and transformed into a "rapid rapids" surfing activity area.
