is there an airport hotel within the airport complex

There is no hotel in the terminal buildings. Many hotels are located near the airport, such as Fliport Inn Haibin Hotel.
It has good service and living environment. The fare is CNY 350 to 400 per night. The distance to the airport is just about 219 yards. So it's very convenient. The hotel is located at the opposite of the terminal building. You can find it easily.
