On September 8, 2043, at 8:30 a.m., except for Li Xiaogang, Zhou Zhuanghe and Ma Wangcai, all the freshmen of Class 4301 sat in the classroom, waiting for the school to arrange military training. After the class bell rang, instructor Liu Xiaojing led two armed police soldiers into the classroom. Instructor Liu walked to the middle of the podium and straightened his body. Squad leader Huo Caixia shouted: "Stand up." The students stood up neatly and said in unison, "Hello instructor." Instructor Liu said, "Hello students, please sit down." "The students sat down. Instructor Liu said: "According to the unified arrangement of the school, starting today, we will start the military training class for two weeks after enrollment. The Central Plains Corps of the Armed Police Force specially dispatched a platoon of armed police comrades to guide our freshmen in military training. The two fighters in charge of our squad are Yan Shuangyou and Kan Lixin. Let us welcome the two instructors with warm applause. The classroom burst into warm applause, and in the warm applause, two armed police instructors walked to the middle of the podium, while Instructor Liu gave up his position in the middle and stepped aside.

The two armed police soldiers came to the middle of the podium and saluted the students, and the two said in unison: "Hello students. The students applauded again. After the salute, the taller and thinner armed police soldier said, "My name is Yan Shuangyou. The shorter, fatter warrior said, "My name is Kan Lixin." Yan Shuangyou said: "Assigned by the superiors, in the next two weeks from today, my comrade-in-arms and I, Comrade Kan Lixin, will be responsible for guiding the military training tasks of our 4301 class. The classroom burst into applause again. Instructor Liu said: "Students, you are the hope of the motherland, and in the process of building the motherland, you must not only have a high level of scientific and cultural knowledge, but also have a healthy physique and excellent military qualities, so that you can become the pillars of the country." Conducting military training and education among college students is an integral part of college students' patriotic education, and is also an important form of enhancing students' sense of danger and establishing a sense of responsibility for defending the homeland and the country in peacetime. Therefore, during the next two weeks of military training, the students must obey the order and listen to the command, and the students must unite and cooperate to complete this year's military training tasks. ”

The students said in unison, "Have confidence." Instructor Yan Shuangyou said: "Be louder, do you have confidence?" The students said loudly, "Have confidence." Yan Shuangyou said: "Very good." Instructor Liu said: "Students, I still have some things to deal with, and the following time will be arranged by the two instructors." Instructor Liu greeted the two instructors and left the classroom in a hurry.

Instructor Yan Shuangyou said: "Students, let's move freely first, and after ten minutes, we will gather on the playground." The two instructors took the lead out of the classroom, and the students walked out of the classroom and walked to the playground one after another.

At nine o'clock, the temperature was already very high, and the students were wearing training uniforms, training hats, and rubber shoes on their feet. When the whistle blew, the students ran from the shade of the trees to the instructor to assemble. Instructor Kan Li stood at the front of the queue and said loudly: "Students, I will lead you to complete our first queue training class today. All of them, take a break, stand upright, look to the right, look forward. Following the instructor's command, the students made movements.

After watching the students do this set of movements, Kan Lixin's instructor said: "Everyone is not doing very standardly, please watch me do the movements." The new instructor Kan Li, standing at the front of the queue, shouted to himself: "Take a break, stand upright, look to the right, and look forward." "I did a standard action according to the password. Instructor Kan said, "Have you seen it clearly?" The students said, "I see it clearly." Instructor Kan said, "Okay, let's do it again this time." ”

The training was boring and tasteless, the weather was hot and sweaty, and the atmosphere of the students' training was not as high as it was at the beginning, and the mood was a little low. Seeing that everyone's sentiment was low, Instructor Yan Shuangyou said: "The weather is too hot, let's make a game and throw away the handkerchief." "When I heard that I was going to play with the handkerchief, the students' interest suddenly increased. Everyone retreated to the shade of the tree and formed a circle, and Instructor Yan Shuangyou took out a red checkered handkerchief from his pocket and handed it to the squad leader Huo Caixia.

Huo Caixia took the handkerchief and circled around the classmates, but the handkerchief in her hand was gone. The half circle of people she walked through turned to look behind her. Jiang Zhu picked up the handkerchief from the ground and went to chase Huo Caixia, but Huo Caixia calmly squatted on Jiang Zhu's vacant seat.
