In the year 825 AD,
In the first year of the Baoli period of the Tang Dynasty (825 AD), Bai Juyi served as the Governor of Suzhou and traveled to the ancient town of Mudu and the surrounding famous mountains. On Tianping Mountain, he left behind a famous poem that says, “On Tianping Mountain, there is a White Cloud Spring. The clouds are originally without intention, and the water is naturally serene. Why does it rush down the mountain? It only adds ripples to the world”.
