Chairman Mao: … In the field of education, the old system must also be changed. The main approach is to combine education with productive labor—studying on one hand and working on the other. Have you ever seen schools like this?

Marochkin: I have visited a few. The students seem very happy, and they are able to produce actual goods right in the laboratories.  Chairman Mao: This is both a historical issue and an international one. It is historical because for many years education has been separated from labor. It is international because this has been the case in every country. By combining study with labor, students will not only acquire scientific knowledge but also practical production skills.
