I didn't know an underground city existed so far out - it had shops, restaurants and everything. It kinda reminded me of Pudong in a way - you can get everywhere through underground walkways and when you get up to ground level, you realize you're in the middle of a futuristic city full of glass and steel.
I do apologize for the lack of pictures, and the lack of quality. I had to be very careful not to smudge my nails.
