I want to go to Shenzhen for a week ~ but staying in a hotel is too expensive ~ more than 200 a day ~ is there anything cheaper ~

The most common hotel costs more than 200 yuan a day, and some tenants who want to rent out their houses at the cheapest price are generally subletting for a short period of time, and the charge is also cheap, just a few tens of dollars. You can see their benches and signs on the roadside. But it's not safe. You'd better go out and play in the hotel. Clean, safe, secure, play without any worries. Have fun!
