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. This social practice of "three rural areas" has enabled me to understand my social position, define my mission on my shoulders, and further stimulate my enthusiasm for learning. 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.

I don't even know what they are, However, no one can see that landmines play an important role. In order to be able to withstand the possibility of a similar attack, The company commander sent four comrades to re-mine, We provide cover up there, As a result, they had just finished their cloth and were ready to come back. That is, the time of the front and rear feet, Another batch rushed up below, This time the number is much higher than last time. I took a look at it, It is estimated that there are at least 30, When the reaction comes back, They rushed up to the four comrades, The two sides mingled, Dare not throw grenades, Afraid of bombing one of his own, Shooting is also restricted, Still afraid of accidental injury, With such a delay, three of the four comrades were tackled by those things, and the remaining one was quick in legs and feet. I remember he first shot with his backhand and knocked out the one closest to him, and then he wanted to save people. Besides the company commander, there was also a platoon officer on our side.
