During the War of Resistance Against Japanese Aggression, people found an interesting way to transmit information. In particular, when the Japanese army suddenly went out of the city to sweep away, how could they notify the anti-Japanese base areas in time? In the Japanese Army

During the Sino-Japanese War, people found an interesting way to transmit information. In particular, when the Japanese army suddenly went out of the city to sweep away, how could they notify the anti-Japanese base areas in time? When the Japanese army carried out a rush of motorized infantry, there was little time to react.

In fact, the masses of the people pretended to be herding sheep or cattle, and then waved the whip in their hands with a crisp sound. These whips are supersonic sonic booms, because in rural areas of China, there are no high-rise buildings, and the sound travels far, far away, even up to about two kilometers. The crisp sound of these whips transmits information like Morse code.

Then, shepherds or cattle herders two kilometers away also began to wave their whips to deliver the message, and soon the information was transmitted to the village or anti-Japanese base area. Through the loudness and frequency of the whip, everyone understands the number, weaponry and direction of the Japanese army. Some even greeted the Japanese soldiers while herding sheep!

This discovery shocked me for a whole year.

Why did I be shocked by this passage? Because under the conditions of the time, the people used this creative way to convey information, showing their ingenuity and tenacious spirit of resistance. This made me deeply feel the strength of the people and the firm belief in the war of resistance.
