What are the four-star hotels in Putian?

Sure, Tian Fei Hot Spring Hotel. It's marked on the map.

Oriental International Hotel, standard four-star. The built-in facilities are quite good and worth recommending.

Huatian (Jinye) Hotel is also a four-star hotel.

There is also a hotel in Taiwan Province Province. I don't know if it's ever been opened, but it's also very luxurious.
