Any hotel in side Nanshan Temple? And offer free entrance?

I am afraid that there is no hotel inside the temple. But, you can stay at Nanshan Hotel inside the cultural tourism area. It is to the opposite of the statue of the Goddess of Mercy. A standard room costs around CNY 500 per night. You can book a room by dialing 86-0898-88838088.

You need to pay the entrance fee of CNY 150. You can ask the staff whether they provide some discount. Good luck!
