How much is the air ticket from Dalian to Qingdao?

I'll post the website of Shandong Airlines for you.

You can buy it directly from the internet, and it is still very cheap. I see the cheapest one is at night, as long as 160.

Besides, I think small hotels are rarely safe. You can consider going near the university to see if there is a house for students to rent for a month.

The consumption level is not higher than Dalian. In fact, the consumption level is relatively average. It depends on how you spend your money ~ ~
