With the increasing military strength of countries, the destructive power of nuclear weapons is increasing. Countries can no longer make wars as before, and the world is still peaceful. China has always been a peace-loving country. As the saying goes, "If the enemy does not attack me, I will not attack." Since 1970s, China has maintained a long-term peace. But even in this case, China did not give up training his soldiers. The strong quality of China's army also makes the people of China proud and amazes the world during the National Day military parade every year. The first-level preparation is the highest standard of defense, and it will not be issued unless it is an emergency. In 2 1 century, there was no first-class preparation guidance in China. It happened six times in the 20th century.

First-level combat readiness, that is, when the situation is extremely tense and the symptoms of war against China are obvious, shows that the country is at a critical juncture and is the highest level of alert. In the history of China, a * * * appeared six times, the first time was 1950 volunteer army, which completed the position allocation of equipment and improved the action plan. The troops are in a state of readiness. The second time was before 1958 shelled Kinmen, and they were ready to repel the invading enemy. The third time was 1969' s Zhenbao Island counterattack. Due to the strong military power of the Soviet Union at that time, our country made preparations for preventing armed conflicts in advance.

The fourth time was 1976, and it was put on alert because of the death of Chairman Mao. 1979 before the fifth self-defense counterattack against Vietnam, the air force and navy were on standby to support land operations. When the last first-level combat readiness was 1996, in order to prevent external interference, a large number of planes were assembled before the exercise to ensure the success of the exercise.
