There seems to be a Libo car rental company there, and the car rental price is ok. We used to go to Rizhao to play with them. The price is reasonable. Original price 150- 100 yuan/day, we only need 80 in September. You can ask if there are any preferential activities. There is also Rizhao's rental network. You can see that there are good companies, because renting a car now is based on the peak tourist season, hehe.
Please accept it, thank you!
