Hello! The certificate of nine-year compulsory education can be issued directly at the education bureau where your household registration is located (district education bureau, county education bureau and municipal education bureau all have it, some departments are called education committees, and some directly call offices, so you can ask again). This certificate can indicate what courses you studied in which school from which year to which year (such as primary school courses and junior high school courses)!

This certificate can be stamped with the official seal of the Education Bureau. Generally, two seals are required (one for the office and one for the Education Bureau). If it is impossible to stamp two chapters, it is no problem to stamp the chapter of the Education Bureau. You don't need to take this to the notary office for notarization, just have the seal of the Education Bureau.

Above, I hope my answer is helpful to you, and I wish you all the best!
