I want to go to Beijing, Shanghai and Xi 'an for a few days. I don't know how much it costs to go to those tourist attractions. Ask the great god to plan Beijing and Shanghai.

Accommodation is calculated at 300 per day. Tickets for transportation can be compared with the prices of high-speed trains such as Flying Pig and Ctrip. Then the local traffic is calculated according to 100, and the taxi is calculated according to 300-500 a day. This is the price of dinner and snacks that can be halved. Shanghai can be calculated according to 500 a day, and Xi 'an can be calculated according to 300 a day. These scenic spots that can be seen as far away as Taobao can be calculated by choosing a day trip and a package ticket.
