What are the natural mysteries of China?

On the vast Altay grassland in Xinjiang. People can often see standing stone statues. These stone statues are all carved from a whole rock. From the appearance, most of them are lifelike, like heads, faces and bodies. The Alcatel Stone Man found on Alcatel Grassland in Wenquan County, Bortala Mongolian Autonomous Prefecture, Xinjiang, is carved from a whole piece of white sand. It has a broad round face carved on its head, a pair of protruding slender eyes and high cheekbones, two moustaches on its upper lip, a wide belt around its waist, a cup and a lamp in its right hand to its chest, a long sword hanging around its waist in its left hand, and a pair of leather boots carved on its feet. Ancient clever masons carved a small pocket and a small dagger on their belts. The stone man looks dignified and deep, just like a mighty soldier on the grassland. Up to now, there is no unanimous opinion on who carved these stone men and which ethnic tribe they belong to, which is still a mystery to be solved.

2. Why do spontaneous combustion fires of farmers occur one after another?

1989 1 1 At the beginning of the year, a strange thing happened in Xinshao County, Hunan Province: He Ronghua, a farmer in Zhangjia Village, Huaqiao Township, had 12 spontaneous combustion fires in three days. Spontaneous combustion of bedding, firewood and other items. Whether it is wet or dry, few of them are mostly lit from the top, and the flame is red or green. 165438+1At about 4: 30 pm on October 5, He's family was digging sweet potatoes in a field behind their house when they suddenly saw smoke billowing from their home. They rushed back immediately, kicked open the door and found that the quilts, clothes, mosquito nets and armchairs piled on the bed were burning, and the green and red flames jumped to more than 2 meters high. After being put out, the spontaneous combustion articles have been reduced to ashes, but the bed and armchair are intact. Then there were 1 1 spontaneous combustion fires from 9: 00 am on the 6th to 4: 00 pm on the 8th, and 9 of them were witnessed by He Ronghua's family. Spontaneous combustion items include straw beside the pigsty, curtains on the door, pillows on the bed and children's skirts. At about 8 am on the 7th, it was still raining in Mao Mao. A bundle of bush firewood in the open air near the house suddenly emitted smoke from the top and instantly ignited a raging fire. At 6: 30 am on the 8th, the straw on the bed caught fire. After being put out, it was found that the straw only burned the ear and neck. After the incident, Shaoyang Earthquake Office, Xinshao County Science and Technology Commission and Environmental Protection Bureau sent scientific and technical personnel to the site for investigation, but failed to find out the cause of the fire. They speculate that there may be two reasons for Hejia's spontaneous combustion: one may be caused by calcium phosphide, and the other may be a sign before the crustal change. But neither possibility can be confirmed by reliable evidence.

3. Mystery of devil valley in Qinghai.

Qinghai Province has a "devil valley". Whenever people and animals enter the valley, it will call the wind and rain to brew adult and livestock casualties, which is daunting. Why is devil valley so powerful? What kind of "devil" is at work? This valley named "devil valley" starts from Buluntai, Mangya Town, Qinghai Province in the east and ends in Shashan, Ruoqiang County, Xinjiang Uygur Autonomous Region in the west. It is about100km long and 30km wide, and the average elevation of the valley is about 3,200m. This valley has Kunlun Mountain in the south and Altun Mountain in the north. The rainfall is abundant and the climate is humid. Although it is located inland, there are lush trees and rich pastures here. However, this seemingly ideal natural pasture will become a ghastly hell when the weather changes. Wind, lightning and thunder are born on flat ground. In particular, the rolling bombing of Lei Zhen shook the earth, and patches of trees were burned dry. The nearby nomadic minorities have regarded the valley as a forbidden area for thousands of years. Those who accidentally fall in are often struck by lightning and rarely survive. In order to uncover the mystery of "devil valley", geological scientists in Qinghai Province have risked their lives for many times to conduct on-the-spot scientific exploration in this valley, but the reason for this strange phenomenon has never been found. It seems that the mystery of Qinghai's "devil valley" is still difficult to solve at the moment, so we can only look forward to the further development of science to solve the lingering questions.

4. Flowering stones

At the foot of Mount Tai in China, there is a stone culture exhibition hall with a natural stone in it. This strange stone will blossom unexpectedly. This stone is more than 30 centimeters high and looks like a dense white "bud", with its head held high and protruding on the surface of the seal stone. In a few days, these "flower buds" will gradually produce reddish-brown "small flowers" with diameters ranging from 0.5 cm to 2 cm. After the flowers failed, they joined together to form a new layer of stone. According to the person in charge of Taishan Management Committee, this strange stone is a natural bluestone that Wang Zhouxiang, an old man from Gong Li Town, xintai city City, Shandong Province, picked up from the south slope of the village a few years ago and put on the inner wall of his home. Soon Wang Zhouxiang discovered that this stone would not only "blossom", but also grow taller. After the news came out, many farmers around went to Wang's house to see this spectacle. In order to protect this natural stone from being destroyed, Glory Old Man sent it to Taishan Stone Culture Exhibition Hall for display. However, there is still no scientific explanation for this strange phenomenon.
