Where is the cheapest rent in Shenzhen?

How can I put it? The more expensive it is to go downtown, the more I recommend renting a house in Shiyan Luo, Baoan. I used to live in a single room on the eighth floor for 200 yuan a month (of course, there is no elevator). I don't think so. It's prosperous. Where is it near Gong Ming and Songgang (where are many factories now)? If you go downtown, take bus No.392 to Window of the World subway station. I hope you can find a job soon! !
