The art rehearsal room occasionally resonated with the tones of poetry recitation, men and women expressing emotion, praising labor, dedication, and the great landscapes of the motherland.
The night class classroom was divided into two rooms, one on the left and one on the right. A sign for basic culture class hung on the door of the left room.
The so-called basic culture class was commonly known as a literacy class, as the cultural level of frontline workers in this era was generally low, with many not having finished elementary school.
The literacy class mainly taught workers to read and write, so they could read newspapers, understand factory announcements, safety procedures, etc., and have time to write letters home.
Besides teaching literacy, the teacher also taught arithmetic, that is, the four basic operations, simple geometric knowledge, focusing on basic practicality indispensable to daily life and work.
