How much does it cost to travel to Northern Europe?

It depends on which countries you want to go to and when you have time to go. If you go in summer, the air ticket will be 4000-5000 per person (round trip plus 2 domestic segments), the time will be 10-15 days, and the hotel will be 10-15 days. Three-star to four-star, the cost is about 4,000/person, plus other expenses, it is about 10,000. If you are traveling on a budget, you are not included in this list. You can probably get it done with 4,000 or 5,000 yuan. —Yunnan Baiyi
