Xu Xiake
"On the top of Tianzhu Peak, people can admire sun-rise in the east, sea of auspicious clouds in the south, the Cangshan Mountain and the Erhai Lake in the west, and the Yulong Snow Mountain in the north. Xu Xiake (1586-1641), a famous traveller and writer of the Ming Dynasty (1368-1644), marvelled that on the top of a single peak, people could see the "Four Scenes" - sun, lake, cloud and snow. "
