How much does it cost for two people to travel from Changchun to Beijing and Tianjin?

I think you might as well go to Dalian, Yantai and Taishan. Two people save about 5000. You can play in seven or eight days.

If Beijing and Tianjin (in fact, I don't think there is anything special about Tianjin), Beijing is also good, and there are many places to play in the capital, such as the Great Wall, Tiananmen Square and the Forbidden City (this is a cultural landscape, which is meaningless if no one introduces it and no one knows it), but Beijing's consumption is high, so if you want to save two people some money, whether it is driving, eating or staying, it will cost about 6,000 yuan.

You'd better go to the bookstore and read books about self-help tours. You can also see on the internet that self-help travelers have clear instructions on food, clothing, housing and transportation, matters needing attention and how much they spend.
