First of all, teaching can temper the will of college students, thus promoting the improvement of their comprehensive quality. The development of college students' teaching activities has well exercised their team cooperation and management ability, and laid a foundation for their future work and life. At the same time, during the teaching period, through the contact with the working people, college students can derive feelings of respecting the working people and the fruits of labor, and accelerate the improvement of their personality.

Second, teaching can broaden the contact path of mountain students to knowledge and help them to succeed. The educational resources of students in poor areas are not the same as those of ordinary students. The holding of teaching activities is undoubtedly to increase their exposure to mainstream knowledge, so that they can better adapt to social development and benefit the country and themselves with what they have learned.

Third, teaching can narrow the gap in education level to a certain extent. Teaching activities are mainly aimed at students in poor areas who usually lack educational resources and formal knowledge. With the help of national policies, the differences between educational levels can be narrowed, so that students in poor areas with backward education can also enjoy a broader learning world.
