A, Huashan mysterious cave
Why is this "mystery" an eternal mystery? It is because this "cave" is a stunning spectacle of ancient architecture engineering. Because there are no murals, Buddha statues, words and so on. In Huashan Mystery Cave, which is not recorded in history, it is hard to find even in local folklore.
However, the shape of Huashan Grottoes is different, characterized by large scale and dense distribution. It is rare in China, and it can be said that it is a must in China. It is also known as "the ninth wonder on the mysterious line of 30 degrees north latitude". Such a powerful landscape can't be formed naturally, can it? How did it come into being? How did the ancients do it? Who built it? What do they do with millions of cubic stones? Wait, the problem still can't be explained.
Second, the mysterious incident of No.37 Linjiazhai
The mystery at No.37 Linjiazhai was a massacre. When the police arrived at the scene, they found that the house was empty and there was blood everywhere, but no body was found. According to the investigation, the police put their suspicion on a man named Ye, thinking that he probably killed his wife and children.
Legend has it that after the police arrested Ye, they gave him a mental examination and an X-ray examination. The most amazing thing is that this man has no brain tissue, but the police are shocked. He can live without brain tissue. What a nice man! He is in a cold sweat at the thought.
To sum up, there are too many unexplained things left in the history of China, many of which cannot be explained. According to the current level of science and technology, it can be said that no one knows. I hope that science and technology will become more and more developed and these unsolved mysteries will be solved.
