The eonsulate in China should be reform

The Visa officer in Chinese consulate always denied students without any reason. Sometimes they refuse to give students visa just because they are in bad mood, and the students never make any mistake. In shenyang Liaoning, many students have been denied just for the Visa offocer not happy. I'm one of that students. I have an interview in the Shenyang Consulate in 11 May, and I got the interview in the first window. The officer always stop me when i'm answer his question, he never let me finish a whole sentence. I just began the sentence, he has interrupted me. At that day, almost every students who has interview in his window has denied. I think, the goverment should stop this phenomenon that the students denied with ill-founded reason. We all want to go to American to study.
