Introduction to Mizuki Tsinghua University: Mizuki Tsinghua University is the "garden within a garden" of Tsinghua University. Located on the north side of Gongzi Hall, the design is unique. The forests and mountains that change with the four seasons are surrounded by a beautiful water, and two exquisite and elegant ancient pavilions are hidden between the mountains and forests. The lotus pond of Shuimu Tsinghua University is one of the "two lakes and one river" in the water system of Tsinghua University (Shuimu Tsinghua Lotus Pond, Jinchun Garden Lotus Pond and Wanquan River). In summer, the lotus flowers are in full bloom, creating a lush green scene; in winter, white snow falls on the surface of the pond, surrounded by green branches, creating a unique scene. The elegant ancient building on the south side of the lotus pond was originally the back building of the Gongzi Hall. The main corridor of "Shui Mu Qing Hua" has the four characters "Shui Mu Qing Hua" on the forehead. It is majestic and tall. It is recorded that it was the imperial pen of Emperor Kangxi. The four characters "Shui Mu Qing Hua" come from a poem by Xie Huan of Jin Dynasty: "The wind blows the wind, Baiyun Tun Zeng'a, the songbirds gather in Jingzhang, the water and wood clear Qing Hua." Hanging on the red pillar in the middle are Daoguang Jinshi of the Qing Dynasty, Xian, Tong, Guang A famous couplet written by Yin Zhaoyong, the minister of the Ministry of Rites of the third generation, said: "The scenery outside the threshold is extraordinary in the ever-changing spring, summer, autumn and winter. The shadows of clouds in the window are wandering freely from east to west, north and south. It is a fairyland." A waterfall can be seen on the west side of the lotus pond. The water is flowing continuously, and the sound of water can be heard from a distance, which is refreshing. Because of its elegant environment, Shuimu Tsinghua University is often chosen by Tsinghua students as a place to study, study and take a rest.
