There is a magic trick called the Great Change of Living, the magician puts a living person into a black box, the lights change, the music turns, the box opens again, and the person is gone. We all know that magic is fake, but there have been events in history when twenty thousand people evaporated. It happened in 1945, when the War of Resistance Against Japan finally ended and the Japanese Emperor announced his unconditional surrender, but there were still some Japanese soldiers who were still unwilling to accept this fact, and they opposed surrender in their own way - fleeing into Changbai Mountain.
Changbai Mountain is located in the northeast of China, rich in forest resources, diverse species of animals and plants, but the climate was too cold at that time. After the Japanese army fled into the Changbai Mountains, China also sent soldiers to search to prevent them from coming out again and maiming the people of the northeast. Then, even with the use of the air force, there was still no trace of this group of devils. Twenty thousand living people have disappeared, and no one has been able to give a reasonable and well-founded explanation until now.
However, a discovery in 1967 may give an answer to the problem from the side. In 1967, a Chinese expedition encountered an avalanche while surveying Changbai Mountain, blocking the road when it came in. The local guide led them down a little-known path, only to find countless wreckage and dilapidated tents, including a tattered notebook full of Japanese and maps. The head of the scientific expedition handed things over to the state, and after the translation learned that this was in 1942, when the Japanese came to Changbai Mountain to find the entrance with german funding, the specific details could not be verified, anyway, a lot of strange things happened, such as falling into the bottomless pit, the body floating into the water, the radio was interfered with, and the people who went out to find reinforcements never returned...
It turned out that after the all-out war of aggression against China began, the Japanese army stationed a lot of troops in the northeast of our country, and they even established a puppet Manchurian regime, as if they regarded the northeast as their territory to live. According to records, the Japanese would go to Changbai Mountain every year to conduct surveys and surveys. These skeletons were left behind by the survey team. It can be seen that Changbai Mountain is full of mystery, and it is not easy to survive in the deep mountains and old forests. Therefore, some people speculate that after the 20,000 Japanese troops fled into the Changbai Mountains, they died because of the harsh living environment and the severe food supply. However, there is also speculation that these Japanese troops were found by the Kuomintang and incorporated into a unique army that became cannon fodder on the battlefield. At that time, Chiang Kai-shek attached great importance to Japan's military talents and combat strategies, and once he also invited a Japanese officer as his adviser. There is also a possibility that there is a legend that there is a heavenly pool on Changbai Mountain, and there is a mysterious creature in the heavenly pool. In the early days of the founding of the People's Republic of China, it was recorded that this Tianchi water monster was more than three meters long, had a long neck and a large head, and according to later scientific research, it was thought that it might be a marine creature called "sunfish".
So the question is, as China's deepest inland lake, how can there be marine life in Tianchi? The answer is that Achichi and the Sea of Japan are connected. So, is it possible that when the Japanese surveyed Changbai Mountain many times, they found this secret passage to Japan, so they placed submarines here and smuggled the soldiers back to Japan? After all, after the surrender at that time, the Soviets captured Japanese prisoners on a large scale and transported them all to the extremely cold Siberia for coolies, and the number of Japanese who died was countless. Moreover, the innate "samurai spirit" of the Japanese will never allow them to suffer any humiliation, so they will never surrender. Of course, these are just speculations, all based on limited information and unlimited brain holes, welcome to share their views together.
