In Beijing, you might need to look for a location in the suburbs. If your classmate has a residential plot of land, you could probably rent a few square meters from them and set up something there. It should be relatively inexpensive, and someone can also help watch over it to prevent theft or unwanted visitors. However, if you're looking on your own, you might not be able to afford a good location, and setting up somewhere temporarily on top of a hill might be a cheaper alternative.😂
