Yuèqīng
Yueqing lies beside the coast of southeastern Zhejiang, beneath the peaks of the Yandang Mountains. The mountains are celebrated for their cliffs, caves and waterfalls, above all the great fall of Dalongqiu. In 1632 the traveller Xu Xiake climbed the heights to investigate its source. His observations challenged the older claim that the waterfall flowed from Yan Lake, showing the value of examining the landscape rather than relying on a geographical account alone.
