Where does "Wandering Home" come from?

Eryuan County, Dali Bai Autonomous Prefecture, Yunnan Province, with a long history and beautiful scenery, was called Langqiongzhao and Langqiong County in ancient times. Surrounded by mountains, there are streams and trees everywhere, and many villages resemble the beautiful villages in Chengdu Plain. During the Jiajing period of the Ming Dynasty, Yang Shen, the top scholar of Sichuan who lived in exile in Yunnan because of his shame, wrote the poem "I dreamed that I had been here before, and the wanderer was suspicious of returning to his hometown" as soon as he came to Langqiong.
