I want to go to Yuncheng, Shandong, where hotels are more economical and can be booked online.

This is not available. Everything in Yuncheng is very affordable. It is recommended to stay in Yunzhou Hotel. The government guest house is relatively safe and the price is not too expensive. Just west of Tangta Square, near the bus stop, take a taxi to 5 yuan, and walk 15 minutes. The high-end is seven stars, which is very luxurious. I wonder if I can book a room! Don't forget to try Zhuang steamed buns when you go to Yuncheng.
