How much does it cost for two people to visit Qingdao from Xi 'an for two days?

Depends on how you want to play. Personally, I think coming to Qingdao means seeing the sea (I am from Xianyang and have been in Qingdao for 3 years). In Qingdao in August, the temperature is not low at night. Personally, I suggest that there is no need to stay in a hotel. You can camp at the seaside with a tent, and there is a rent of 30-50 yuan. I still suggest that you can find some strategies online. It's best not to join a group. Two days is really a little short, so we can only take a trip along the coastline. I suggest you get off the train, go to the trestle first, you can have a rest and play, and then go all the way along the coastline to Shilaoren, Underwater World and Polar Ocean World, but I won't choose to go again. Olympic Sailing Base is a must.
