I remember that there are large-scale Japanese classes on the third floor of Chang 'an Town Library, including English and eloquence classes, interest classes for adults and children, mental arithmetic and so on. Some children have been sent to study, and the teaching is very formal. If they fail in the first stage, they can enter the next tutorial for free. They can register and read newspapers. I remember there are day classes and night classes, which are more suitable for people who study while working. The library is located at the intersection of Chang 'an Gymnasium and behind Chang 'an Square.
