Hello! Enterprises want to minimize the recruitment risk when recruiting talents. Your resume can be embellished with language, but I don't recommend you to cheat on it. The employer will definitely investigate the contents of your resume. Some content can be learned by asking questions during the interview, and some content can be learned by other means. As you mentioned, if the employer wants to check your CET-4 report card, what will you do?

In fact, it really doesn't matter whether the score of Band Four is high or low. What the employer cares about is not these, but whether you meet its recruitment requirements and whether you are qualified for the position you are applying for now.
