if you find the cheap hotel in shenzhen that;s very danger
Are you sure?
Because I am in a small town now and the 40:- RMB hotels feel safe here.
Of course Shenzhen is a big city.
But maybe there is some 40:- hotel that is still safe.
40CNY/night and feeling safe? Just impossible. I used to live there, the most common hotel that can make you feel safe and comfortable would cost 150CNY at least, anyway if you;re looking for a long term hotel, the price may be lower.
ShenZhen is one of the most prosperous cities in the world where people pay 1 million dollar for average house, so just give up your 40 CNY.
