The cheapest place in Haizhu District must be Chisha Village in Guangdong Business School. I live in a room of 280, with a single room of 15 square meters, with a bathroom. Because it is an advantageous home management, it is already expensive, and the houses rented by my classmates from villagers are only 240,250. If you want to find one near Baogang Avenue, I suggest you search online, which is very complete!
