I am a freshman this year, and the file issued by the school says Shaanxi Xi People's Insurance Bureau. Where is it?

You should go through the relevant formalities at the Talent Center (the first floor of Father's Building in the west section of South Second Ring Road) and get a letter of employment introduction. If you are not a student, you must also get an admission card and then go to the talent exchange centers in various districts to keep the files. It depends on which district you are from. Don't take the documents yourself, because it will bring a lot of unnecessary trouble in the future. It is suggested that the talent center kept in your student's hometown should pay the hosting fee of 180 yuan every July from the second year.
