They all say: "The feelings between comrades are closer than brothers." Yes, it was a comrade-in-arms relationship that was established in the test of blood and fire. The feelings between comrades-in-arms are the most sincere, detached and pure feelings, and they are real heart-to-heart exchanges; That is a sincere friend, without utilitarian color and secular prejudice.
Friendship is the sustenance of life. As the saying goes, "there are soldiers for a thousand days, and there are soldiers for a while." Soldiers are born to fight, although there is no war to fight in non-war years. But anyone who wears a military uniform has a sense of crisis. If the war starts tomorrow. This is not an alarmist. The international situation is changing rapidly, and war will break out at any time. Any soldier is ready to fight the enemy at any time, even at the expense of blood. By that time, the comrades who are with you are the sustenance of life. The profound friendship between the two countries is the result of life and death. On the exercise ground, on the battlefield, you put life and death at risk, leaving safety to your comrades and danger to yourself. This is a song played by comrades with sweat and even life.
People who have not witnessed the scene of soldiers retiring with their own eyes can hardly appreciate that kind of friendship.
