Why did Chengdu sound the air defense alarm on March 25th, 2022?

Today is 9. 18 Anti-Japanese War Memorial Day. I believe that many cities across the country will sound air defense alarms today and cherish the history of the martyrs' bloody war of resistance. Of course, not all cities will sound the alarm today. For example, the city of 1 1 in Hebei will choose to sound the air defense alarm on July 7th every year to commemorate the July 7th Incident. There are also Nanjing, Xiamen and other places, which will choose to sound the air raid alarm on a certain day of each month according to different local conditions.

With the popularization of modern communication tools, our mobile phones can also receive meteorological disaster information in time, and some people will think that air defense warning is out of date. In fact, in some cases, neither SMS nor WeChat can guarantee that most people can read urgent messages at the first time, and it is even more unrealistic to make phone calls one after another. Moreover, there are still many old people and children who don't have mobile phones.

Impressively, there was an earthquake in a certain place in Sichuan two years ago, and the local government issued a warning through TV media. At the same time, the alarm sounds in the community are also one after another, so the role of the alarm is still irreplaceable. Air defense warning gives people the most direct information in a familiar way, which is incomparable to any modern communication tool.

The air defense alarm, like the ancient bell in China, represents a spirit of being prepared for danger in times of peace. In wartime, he was the horn to protect people's lives and property. In peacetime, he is people's memory of past wars. The trial sound of civil air defense alarm is a trial sound in non-emergency situations. It is to better test the integrity of air defense alarm facilities and the sound effect of the alarm, make the general public familiar with air defense alarm signals, and improve the national defense concept and people's air defense awareness.

I hope everyone will not panic after hearing this and fully understand the meaning of different alarm sounds. Besides, we must know how to remember history and worship heroes. Only in this way can our country maintain long-term stability and overcome difficulties. Do you think I'm right? Welcome to discuss in the message area.
