Tianhe Bus Terminal is not a big supermarket, where things are expensive! There is a multi-product supermarket in the north area of South China University of Technology, across Dongguan Zhuang Road. The goods are complete, but also more expensive. Not far from there, there are many supermarkets in Changfu Street because there are many other technical schools, where things are the most affordable! Students who live in north china university of technology usually go there to eat, drink sugar water and buy things! Ask for directions if you don't know!
