Qinghai Lake, which is about 3196 meters above sea level, covers an area of ??4583 square kilometers and is located in the northern part of the Qinghai-Tibet Plateau. It is the largest inland lake in my country. Qinghai Lake is surrounded by mountains. The lake water is clear and blue. The closer you go to the center of the lake, the less buoyant the salty stagnant water becomes. Almost no one dares to go there. A motorized sailboat once tried to push toward the center of the lake, but the boat capsized and sank within a few miles of sailing. From then on, no one dared to take this risk again.

What does the center of the lake look like? Curious people couldn't help but speculate that this is how the mysterious legend in the middle of the lake came into being. Legend has it that the bottom of Qinghai Lake is unusual. There is a bottomless black hole there. This cave leads to the Black Sea in the north, which is transported by the lake water. For generations, water from the melting glaciers of the snow-capped mountains around Qinghai Lake has been flowing into the lake, but there is not enough water to be sent away by the black hole. As a result, the water tide in Qinghai Lake has dropped by 30 to 40 meters compared to hundreds of years ago. The dark gods live in this black hole, crossing the "water bridge", sometimes coming to the lake, and sometimes traveling far away. The stories about black holes and fish spirits greatly tempted the curiosity of a young Tibetan. He risked his life and ventured alone on the ice into the center of the lake. He searched for a long time on the ice in the center of the lake, but could not find anything clear. At the entrance of the black hole, a huge whirlpool was discovered underwater, causing the water to spin around... Later, experts estimated that there might be a strong magnetic field in the center of the lake, causing the water to turn rapidly to form a whirlpool. There may be a "water bridge" opening leading to an unknown destination.

In mid-June 1955, a small group of People's Liberation Army soldiers accompanied a scientist on a scientific investigation in Qinghai Lake. One day, 10 of them took two amphibious vehicles and drove from the east side of Haixing Shandong to the other side. At 12 noon, the weather was hotter than usual and the water surface was calmer. When traveling about 17 to 18 kilometers, squad leader Li Xiaoan found a yellow-black thing about 10 meters long and 2 meters wide 80 meters ahead on the right, with its top basically level with the water. At that time, Li Xiaoan thought he had encountered mossy sand dunes and reminded the driver to pay attention. The "sand dune" was getting closer and closer. When it was about 30 meters away from the soldiers, it could be seen clearly with the naked eye. Just as people were talking about it, they suddenly saw the "sand dune" flashing upward, about 30 centimeters above the water, and then Immediately it sank again and disappeared.

In the spring of 1960, during the peak fishing season, fishery workers were fishing in the lake. Suddenly, the workers discovered that huge waves suddenly rolled up on the water in the middle of the lake. In an instant, they saw a black "giant reef" gradually rising from the water, resembling both a turtle shell and a whale's back, like an unnamed island. . After a long time, I saw the "black reef" swaying, stirring up another huge wave, and then sank into the water. This scene appeared several times, surprising those who witnessed it! People have spread rumors that they are suspected to be the manifestations of thousand-year-old fish spirits, turtles, and the like.

On the afternoon of May 23, 1982, employees of the No. 2 fishing boat of the Fifth Brigade of Qinghai Lake Farm witnessed the "water monster" again. The weather was sultry that afternoon and the lake was calm. At about 4 o'clock, the fishing boat began to return. Later, two workers standing at the stern of the boat saw a huge yellow-black monster moving on the water 20 degrees east of Haixing Mountain. It looked like a sampan boat turned upside down and was slightly larger than a sampan boat. , head and tail not exposed, about 13 to 14 meters. This water monster immediately attracted attention, and the helmsman immediately turned the bow of the boat and headed straight for the monster. However, the boat sailed about 50 meters away from the monster. Perhaps because the fishing boat made too much noise, it alerted it, and the monster immediately dived into the water. From the time the monster is discovered to the time it dives, it takes about 5 minutes. When diving, the monster's body shone like fish skin, and a wide and large swirling current appeared on the surface of the water, which lasted for a long time. Happily, the fishing boat record book records the entire sighting in detail, providing first-hand authentic and reliable written records for the study of Qinghai Lake monsters.

Comprehensive analysis of these three sightings can lead to the following conclusions: First, the weather was relatively muggy before the water monster appeared; second, the water monsters witnessed in the three times were all larger in shape, black in color, and characterized by activity They all surfaced for a while and then sank immediately, with a length of more than 10 meters. From this, it can be concluded that the three water monsters are similar objects; third, they all appeared between Haixing Mountain and the east coast of Qinghai Lake.

Scientists speculate that the Qinghai Lake monster is not very similar to ancient reptiles such as plesiosaurs, because the monsters that appeared three times all had hidden heads and tails, without tall humps, which are not consistent with snakes. The living habits of neck dragons.

For many years, Tibetans on the banks of Qinghai Lake have always regarded flying eagles in the sky and fish swimming in the water as gods, and never harmed or caught fish. Over time, the fish in the lake multiplied to the point of saturation, and large fish weighing several 10 kilograms were very common. common. Although there are now state-run fishing grounds for fishing, it is not known whether there are still rare large fish left in the lake. Of course, it is not credible to say that the water monster may be a big fish, because the largest freshwater fish cannot grow to 13 to 14 meters in length. According to literature, freshwater fish that grow to 5 to 6 meters in length are rare.

The mystery of the fish spirit in Qinghai Lake has attracted the attention of the world's scientific community. We look forward to unveiling the mystery surrounding it as soon as possible.
