In the east valley, Guling, Lushan Mountain, there is the winding and twisting Changchong River. On the banks of Changchong river lies a British arch-style house hidden amongst the depths of the greenery. It is the old residence of Chiang Kai-shek and Song Meiling in Lushan and it was personally named “Mei Lu” by Chiang Kai-shek himself. Mei Lu lies within the unique urban landscape in Lushan, presenting a view of China's changing and turbulent modern history.
