We all know that Japan borders us and has always been eyeing our country. After Japan's reforms, the country's military strength has continued to increase, and it has a great appetite to swallow China and even the whole of Asia.

A real victory or defeat, in addition to depending on the strength of the two sides participating in the battle, intelligence information is also a crucial link. During the War of Resistance Against Japan, the Japanese army was long stronger than our country in terms of combat effectiveness, and its weapons were also more sophisticated than ours. What is even more frightening is that the depth of Japan's study of China is staggering. As an invading country, Japan's familiarity with China's topography is frightening, from a village to a century-old tree, which is basically on the map of the Japanese army.
Before the outbreak of the war, the Japanese side sent countless people to China for field investigations, mapped and measured the country's territory, and accurately measured most of China's major cities. Take the map of Beijing at that time, not only most buildings have notes on the map, but even the names of each road, the names of wells, the names of temples, etc., are marked.
Maps of all parts of China in the hands of the Japanese army were illegally drawn in the decades before the beginning of the war, in the name of tourism, and the Chinese at that time had no concept of mapping, which made the behavior of the Japanese more unimpeded. For example, on the eve of the outbreak of the war of aggression against China, Yan Xishan's classmate Itagaki, who was in Japan at the time, once wandered around under the pretext of travel, but he did not expect that people had a purpose, and they examined Shanxi clearly, and even which bridges could pass through what weapons and weights.
At that time, the Japanese studied China thoroughly, and even Chinese themselves could not compare, just to say that this "tourist map" could be directly used as a military map. For the study of Chinese, the Japanese army also has a lot of experience.
In 1936, Takayoshi Matsumuro, the head of the Japanese secret service in Peiping, submitted a secret report to the headquarters of the Kwantung Army, which read: "Most individuals or small groups of prosperity lack the concept of being a citizen, so they form a situation of hegemony, dictatorship, and private people." They shall not be responsible for the survival of the nation or the suffering of the nation. Their political and material desires are very strong, so they are not willing to crush their power except to maintain the status quo in order to solve their desires. There are very few people who can really love the country and serve the people, and most of them care for themselves and do not care about others. ''
For ordinary people, Matsumuro Takayoshi also believes that the characteristics of Chinese are patriotic for only five minutes, and even those who do not know what the country is. ''
