The deputy director of the Meteorological Bureau said it was impossible to send early warning information to the people of the whole city. It's slow, right?

Although I am not a professional, I know that sending too many short messages at a time will take up too many communication resources and affect normal communication. However, this situation can be avoided by sending in a specific sequence of segment numbers. Even if some people receive text messages in time, it doesn't mean that they can't get relevant information, because they can get disaster-related news through the people who receive text messages. For example, your boss received it. Although you didn't receive it, your boss will inform you, even if you don't. The boss ran away first, and the boss disappeared. You had a premonition that something was wrong. You can also run away. . . Therefore, disaster early warning is very necessary, even if the disaster has occurred, it can also reduce the potential losses. When it comes to responsibility, there is no question of timeliness, but whether you have notified it. My place is Fuzhou, and we often have typhoons here. Basically, major typhoons are notified by SMS. Also, China Unicom is not the only mobile phone operator.
