China's Chinese characters are the world's longest time and there has been no fault in the text, the current known system, the earliest Chinese characters are oracle bone, in addition to the Chinese characters derived from the words have disappeared, but the Japanese language retains some Chinese characters, but some words have different meanings from China's Chinese characters, such as the Japanese "niang", in fact, the meaning of "daughter", but in the Chinese, it is "mother".
As we all know, in war, intelligence is very important, "Sun Tzu's Art of War" said that "know each other and know each other, never lose a hundred battles"; World War II is the largest world war in human history, in order to steal enemy intelligence, to prevent the enemy from stealing intelligence, each country is doing its best and showing its own ability.
Among them, the mathematician Alan Messison Turing once helped the Allied military crack the famous German cryptographic system enigma, thus helping the Allies to win, and his contribution was not only to end the war, but also the beginning of modern computers and artificial intelligence.
The contribution of Alan Messison Turing is great, but the invaders are abhorrent, Japanese imperialism has done a great deal of preparatory work before waging war against our country, and Japan has always had a relationship with our country, and japan knows a great deal about our situation.
Initially, the Japanese army won victories in battles due to stealing our intelligence, but we could not not use the telegraph because of this, and at the end of the Qing Dynasty, the minister Li Hongzhang was able to open the General Telegraph Bureau with the principle of "using soldiers in the way of using soldiers, speed is precious".
However, after our army has suffered losses, it is natural to come up with countermeasures, and our country's cultural heritage is also very deep, at this time the dialect comes in handy, "three different tones, ten different sounds, a hundred miles without language", such as "are you just right", is the meaning of "do you eat", this is still relatively simple, more complicated, even if you know Chinese characters, you may not be able to understand its meaning.
Even if there are many traitors who betray the country and fight for the Japanese army, will they be able to decipher all the dialects of our country? Moreover, the Japanese army also had to find out the dialect of which part of the country was in which part of the country, and then find a local to decipher, which was a very time-consuming deciphering project.
It is understood that in the Battle of Taierzhuang, our army used the Bai dialect of Dali, Yunnan Province, to make military calls, even if it was heard by the Japanese, they were confused, for example, the Bai pronunciation "Bin" means "salt"... Therefore, even if the Japanese army successfully intercepted our army's telegram, even if they knew every word, they were blinded after combining.
In addition to the Bai language, there are also very few people use the Yan dialect, Yan dialect belongs to the dialect of Guanhaiwei Town, Cixi City, Zhejiang Province, China, this dialect should have first appeared in the Ming Dynasty general Qi Jiguang resisted the Wu, Qi Jiguang commanded by the Fujian soldiers brought the hometown dialect here, and then combined with the contemporary language, it formed the Yan dialect.
For example, the pronunciation of "Drum Laoshan" in Yan dialect refers to "praying mantis"; the pronunciation of "Dangyi" in Yan dialect means "bench"...
But whether it is Mandarin, or dialect, in fact, it also reflects the charm of Chinese language, as well as the cultural heritage of our country, for Chinese, will speak the local dialect, does not prevent everyone from learning Mandarin, and can also understand some other regional dialects, and in the view of foreign scholars, people in various dialect areas in China can not talk, so they feel that they are very independent languages.
