Can I call and ask if my personal file includes junior college and undergraduate course?

Of course.

Call the company's archives management office for consultation or call the talent center to check the archives education. You can ask whether the personal archives include junior college and undergraduate courses.

Where should the documents be stored? People with work units usually store the documents in their own work units. If the work unit is small and there is no condition to store files, the employee files will be stored in the local talent market by the unit.
