Let me help you analyze it.
First, the document is unlikely to be sent to you anywhere.
There are two reasons: first, it is impossible for the school to strictly adhere to this time just one year after graduation, because the graduates of 10 are still busy; Second, the document is very important, so it is unlikely that it will be sent directly without contacting me. After all, someone needs to verify whether it is received correctly. If you lose it, it will be very troublesome. Based on this, it is unlikely that the schools and teachers in charge will mail it before contacting you. Of course, it is necessary to take care of the files yourself.
2. Where will the document be mailed if it is mailed?
This involves whether you applied for a registration card at that time. If you have a registration card, you can only mail it to the unit printed on the registration card. It is not standard to send it to other places. If you don't apply for the registration card, the school can't just mail it to you.
3. What should I do if the document is not mailed?
Contact the counselor at that time or the teacher who kept the file. If you can be flexible, you'd better keep them for another year (I think this should be no problem). If you can't be flexible, one can be mailed to the unit printed on the registration card, and the other you can find a unit or sign a contract with the talent market to put it there. It may not be possible to file by yourself. Under normal circumstances, the school does not allow individuals to bring files, for fear of loss, and for other reasons, most units do not accept files handed in by individuals. It is also responsible for students.
4. What should I do if the document is mailed?
Tell the school teacher where the documents have been sent. Then report to the receiving unit to confirm whether the document has been received. Make sure the file address is correct when registering for the postgraduate entrance examination.
To sum up: what you need now is to communicate with the school, look at the current situation of the file, and then do as I say, which is generally no problem.
I wish all the best!
(Supplement: The registration card is divided into the upper part and the lower part. The upper part is blue and the lower part is white. The lower part is put in the file, and the upper part is held by yourself. Students looking for a company usually send their registration cards to the company. Students who are not looking for a job are sent back to their hometown, but the origin of each province is different. It may be the prefecture-level personnel bureau where you signed up for the college entrance examination. It may also be the employment guidance center for college graduates in the province, and the institution in Henan Province is the "Information Consultation and Employment Guidance Service Center for College Students in Henan Province". Of course, although you are a graduate of Zhengzhou University, it depends on whether you are a student in Henan. If not, it depends on the specific office in your province. Go to the school first to make sure that there are no files. If you are admitted to the graduate school, you will lose your registration card. If you have lost it, you still need it.
