On June 16th, I want to charter a car to the Helan Mountain Scenic Area mainly to see the petroglyphs, and leave at about 8 o'clock in the morning. Return to the city by 3:00 pm. 2 people, how much is the chartered car? Those who are willing to carpool together can also get in touch. In addition, how much is it if you send it directly to the airport from Helan Mountain?
