Where is Yuan Tiangang's hiding place?

After Yuan Tiangang and Li sawed off Long Mai, they fell in love with Langzhong, a land of geomantic omen. First, they watched the astronomical phenomena and studied astronomy in the houses built in Panlong Mountain. Later, they built a temple near the Xijiang River and lived in seclusion to study Feng Shui. They were also buried in Guanjiashan and Wulitai in Tiangong Township, Langzhong City.
