Good schools are generally within the Third Ring Road, so we can look in this direction: in fact, the first choice of schools is to look at works, and the second is to look at services. Looking at the works is to see whether the works of your school are fashionable, whether the works are suitable for the needs of work outside and whether they are suitable for your own study. Looking at the service depends on the overall teaching quality of the school, the patience of teachers to guide students, the learning atmosphere of the school and the employment arrangement.
