I don't know. There doesn't seem to be many camping places nearby. Qingxiu Mountain can be considered.

Or the ancient town of Yangmei. I went there once by bike last time (but there is a hotel there)

There is basically nothing to camp in the west and south. If you want to go to the east and north, there seems to be a reservoir to go to Wuming, which should be good.

You can consult the donkey friends of Time and Space Network.
