We are the builders of the future of the society, so we should use our hearts to walk out of the ivory tower and go into the society to understand the national conditions and serve the society. The social practice of "three rural areas" in summer is an effective way to let us know the society, serve the society and exercise ourselves.

I deeply realize that teachers are role models for students, and our words and deeds are seen by students. Therefore, while teaching students, we should also strive to improve our comprehensive quality.

This summer's social practice has not only cultivated our potential to apply theory to practice and the spirit of teamwork, honed our strong will, but also realized the goal of "serving the society and exercising to become a useful person" in the process of social practice. I remember someone once said: whether a graduate is a talented person or not depends on his academic qualifications and social practical experience. Because theoretical knowledge alone is far from enough, without any potential for social practice, one cannot connect with the rapidly developing society. So there was this dragon neck trip.
