When you come to the new campus, you can go from Baoji to Xi 'an, and you can choose trains and cars, which are very convenient. Most of my classmates choose cars.
When you arrive in Xi 'an, the school will send a school bus to pick you up at your new campus a few days after you report for duty, but I suggest you not to choose because there are more people and fewer cars. It takes a long time to wait in the waiting room, but it may not be long if it is early (it is a good choice to wait for the school bus by train).
If you don't want to take the school bus, it is suggested to take a taxi to Huxian at the intersection of Xiwan, and each person will drive to 10/2 yuan. This is Hu Xian's car. Anything over 12 is blackmail. He will drag you to the school gate.
I hope you can get to school smoothly, and you'd better sign up early, otherwise there will be many people who want to help you.
