A gentle breeze brushed over the sea, and the waves gently patted against the breakwater. The sailors returning from a long voyage have once again made the seaside training ground lively. After a crisp whistle, two agile figures leaped up and engaged in a competition on the horizontal bar. On the side of the competition is Sergeant Dong Guofeng, a first-class officer of the Navy's Yellowstone, while his opponent is Private Yin Bohui, known as the "physical expert". I saw Dong Guofeng tightly gripping the horizontal bar with both hands, his waist and abdomen suddenly straightened, his arms muscles instantly tightened, his body moved up and down, and his movements were standard and beautiful. Amidst the cheers of his comrades, Dong Guofeng ultimately won the showdown by a narrow margin. Looking at Yin Bohui, who was somewhat dissatisfied, the taciturn veteran just patted his shoulder and silently returned to the team. "Dong Guofeng is the pride of our group of soldiers!" Hou Feiyue, a second level sergeant who enlisted with Dong Guofeng at the same time, talked about his high school classmate, and his conversation immediately opened. 25 years ago, a train pulled two people to a seaside town. The first time I saw the sea, the first time I went out by boat, the first time I landed on Shanghai Island, Hou Feiyue and other new comrades were excited beyond words, while Dong Guofeng remained calm like an old soldier. It was precisely with this calmness that Dong Guofeng quickly stood out among the new recruits. After the new recruits completed their training, Dong Guofeng and Hou Feiyue were assigned to different submarine hunting units. At the moment of parting, Hou Feiyue could see that besides reluctance, Dong Guofeng's eyes were full of expectations for the future - at this moment, he was one step closer to realizing his cherished dream of becoming a sailor! Shortly thereafter, Dong Guofeng celebrated his first voyage with a boat. That day, the dense dark clouds in the sky pressed low on the sea surface, and the sea breeze howled and rolled up surging waves, fiercely hitting the ship's hull. Sitting in the narrow cabin, Dong Guofeng tightly grasped the handrail and tried to stabilize his body. But as the boat kept shaking, he couldn't help but bend down, cover his stomach, and vomit. In fact, at the beginning of boarding the ship, Dong Guofeng heard a catchy saying: "If you don't board a minesweeper, if you don't board a hunting submarine." On this voyage, Dong Guofeng completely understood the meaning of this saying: only a few hundred tons of hunting submarines, once they encounter strong winds and waves, the degree of turbulence is comparable to that of going into the sky and the earth. Looking at the old soldiers in the stuffy and narrow cabin, who were standing still in battle, Dong Guofeng wanted to hold on and fight with them. However, the constant discomfort that surged over him still knocked him down. From then on, Dong Guofeng not only focused on improving his physical fitness, but also focused on his position whenever he had time, saying, "Even if he couldn't overcome seasickness when going out to sea, how could he still be a sailor!". High frequency operation exercises have left his hands covered in calluses. Hard work pays off to those who have a heart. During his service in submarine hunting, Dong Guofeng won two professional martial arts championships and was awarded the title of "Level 1 Technical Expert" twice. In 2013, Dong Guofeng's unit was equipped with a new type of frigate - the Huangshi. After careful selection, Dong Guofeng became one of the first crew members of the ship. Excited, he didn't expect an old face to appear in the team that was picking up the ship with him: Hou Feiyue! After years of hard work, both have grown into outstanding players in their respective positions. But when he was officially appointed, Dong Guofeng made a puzzling choice: to give up being unauthorized
