I am in Harbin. I want to travel to Mount Tai in Shandong and see the sea. How much does it cost to join a self-help tour?

I'm not a great soldier, so I'll tell you what I know first for your reference. I'm going to Taishan and Qingdao tomorrow. Because I couldn't buy a ticket to join the group, I reported the cheapest one, which only included train tickets, short-distance tour buses and 2 days' accommodation, and I didn't book a return trip. 628 per person minus 200*** to pay 428, as a train ticket, there are more than 300 good cars, and the cars booked by tour groups are the cheapest. I think if the service is too bad, I will play by myself. Book a plane ticket from Qingdao to Harbin at a 20% discount. I made a rough calculation, and the family of three deducted 8 thousand-9 thousand.
