In p>966, when the Cultural Revolution broke out, I was in high school. Junior high school students in six grades. What is "Senior Three"? It's not just that people who read senior three years ago are called "senior three". No matter whether you are an undergraduate, a master or a doctor, whether you are a professor, a high-ranking official or an old man who is laid off, retired or in the countryside, only senior three students who were studying in 1966 will be called "senior three".
