I have been rejected 28 times. How should I prove my student status?

Hello, I am a college student from China. I tried 28 times and sent a variety of supporting materials such as student ID, campus card, university admission notice and online verification report of the Chinese Ministry of Education, but they were all rejected. I also tried github support and they sent me a rejection email within a minute. How can I prove my student status? I think I need a real person to review my proof materials, not a robot. Below is my university acceptance letter
