Blind evaluation refers to the evaluation that needs to be conducted by teachers who are not in school, or local experts, or teachers from other schools. This process is called blind examination of papers. Blind examination of test papers will be stricter than direct examination in schools. If one party fails, its test papers will fail.

I think this is the most important thing. An unclear blind test still needs some luck! Of course, if you want to have good luck, you need to work hard on weekdays. The harder you work, the luckier you are!
