What should I do if my parents' age is not written on the graduate registration form?

If the age of parents is not written on the graduate registration form, you can consider contacting relevant departments or schools to see if you can supplement or correct this information. Specifically, you can consult the relevant person in charge of the school or the Admissions Office to understand the specific processes and requirements for supplementing or correcting relevant information. If the information you fill in is incorrect or incomplete, you can correct it by supplementing materials or modifying the application form. When dealing with such problems, it is recommended that you keep active communication, provide relevant materials and certificates, and solve the problems as soon as possible, so as not to affect subsequent employment or other related matters.
