Introduction to the Valley Pavilion: Zheng Mingyu was born in 1901 in Beijing. In 1938, he moved to Hanzhong via Xi'an. In 1945, he donated 8 taels of gold to build a Lotus Pavilion in Zhangliang Temple, and Yu Youren inscribed "Gu Gu Pavilion" on his forehead. This garden was built during the Xianfeng period of the Qing Dynasty. It is far opposite the North Garden. There is a clear lake in the center of the garden, and a spring gushes out from the side rocks of the pool. A small pavilion stands in the middle of the pool, with a hexagonal helmet top and a flying spine. The southeast is surrounded by curved corridors and rooms, named "Five Cloud Tower". On the northwest side, there is a purple bamboo floor as a screen. There is a tall and straight gall tree beside the pool, with dancing branches and an umbrella-like crown. Before liberation, China's first international travel agency opened here. There was a Bihu Colorful Pavilion in the front, a singing spring and a stream in the back, purple cypresses steaming in the distance, birds singing and flowers nearby, and the surrounding trees covering the area.
