Third, the source
The Soviet version of the sixth grade primary school text "Confucius has a spring" Volume II: By the grassy river, disciples are surrounded by teachers, some squatting and some sitting.
The text "Tomorrow, we will graduate" published by the sixth grade primary school Su Jiao class: the grassy playground, the classroom with bright windows, the naive classmates, the amiable teachers and the ink-filled textbooks are all so attractive.
