If you don't care, you can choose to call back your student source directly, which is the talent market where your high school is located. Similarly, when you need to transfer, you have to pay the storage fee.
Finally, if you want to have a job when you graduate, and your unit is more formal and has the right and strength to keep personnel files, you can directly transfer your files from school to your work unit through the personnel department of your unit.
The above is my own personal experience, but also the personal experience of my friends. If there is any truth, please add points.
