In the following days, the students of the Second Middle School continued to participate in labor. According to the schedule, the practical courses in East Africa were divided into three categories: manual labor, equipment, and industry, each lasting one day, two days, and half a day respectively.
Manual labor referred to the work done by the East African Black Slaves, using relatively primitive tools to carry out a series of agricultural activities, mainly relying on human power to complete.
Equipment primarily involved work done using oxen and horses, or hand tools, which could greatly save human resources, but still relied on manual labor.
Finally, industry signified the mechanized era of agriculture. Currently, no country in the world had realized agricultural mechanization, so this area could only rely on imagination.
This meant that the last half-day course was still theoretical, and students had to go home for a holiday in the afternoon, hence this arrangement.
