Introduction to Songlai Pavilion: Songlai Pavilion, also known as "He Tower", was built in the 1920s and was the residence and office of He Yingqin, the Kuomintang's military and political minister during the Anti-Japanese War. Located on the southeastern slope of the main peak of Huangshan Mountain, it has a bird's-eye view of the shallow valley of Huangshan Mountain. This building imitates the Japanese style. There is a crescent-shaped "Tingsong Terrace" in front of the door. It is said that it was the place where Yingqin practiced Tai Chi.
