There is a mysterious cave in Shiyan, Hubei Province, which spits tens of thousands of kilograms of fish every year. After the experts arrived, they were heartbroken. What happened afterwards?

There is a mysterious cave in Shiyan, Hubei. Tomb-Sweeping Day spits out tens of thousands of kilograms of fish every year. It sounds amazing, like a gift from heaven. The local villagers also think so, scrambling to get near the cave.

With the report of the incident, this incident has aroused widespread concern. When the expert group rushed to explore the cave, they were heartbroken. It turned out that the fish caught by the villagers was the national protected animal "scaly white turtle".

Why does Tomb-Sweeping Day "spit fish" in the cave every year? What is the origin of these fish? This village is not special. Located in the remote area of Shiyan City, Hubei Province, the village is small, with only dozens of families. The villagers work at sunrise and rest at sunset every day, day after day, year after year, and have worked hard all their lives, but they have not been able to get rid of the poverty in the village.

Many young people have gone over mountains and mountains to seek development outside, and the village has become more and more deserted.

Until one day, this deserted village suddenly became lively. The villagers found that in a cave at the foot of the mountain, a lot of fish flowed out of Tomb-Sweeping Day every year. The number and size of these fish are amazing, and their meat is very delicious, with tens of thousands of kilograms flowing out every year.

The villagers think this is a gift from heaven and a reward for their hard work every day. Since then, every year in Tomb-Sweeping Day, villagers have been fishing outside the cave, and it only takes a few minutes to catch a full bucket.

The villagers also know that such things can't be publicized. The more people know, the more their gifts will be taken away by others. Therefore, every household has a tacit understanding and keeps silent about spitting fish in the hole.

Unfortunately, there is no windtight wall in the world, and villagers in several nearby villages also smell some information. The "Cave Fish Spitting Event" spread more and more widely.

People are curious to find out, more and more tourists come here to visit. The bleak and desolate village suddenly became lively.

Soon, expert groups arrived one after another. After investigation by experts, it was found that these fish were inedible. The villagers suddenly panicked. Is this fish poisonous? The whole family used to eat a lot.

Why can't this fish be eaten? Everyone is full of doubts.

The expert explained the reason. It turns out that this fish is a national protected animal, and its name is "scaly white turtle". It existed on the earth tens of thousands of years ago and is called the "living fossil" in fish!

The reason for spitting fish in caves is actually not a foreign land, let alone a so-called "gift falling from the sky", which is a natural phenomenon. It is inseparable from the natural environment here.

Because this cave is soluble limestone, it releases heat when it meets water, and the water level rises in winter, so the temperature inside the cave is higher than that outside. This kind of fish likes warm environment, so they go to caves to keep warm in winter.

The following spring, around Tomb-Sweeping Day, with the temperature rising, they swam out of the cave again, thus forming the phenomenon of "spitting fish in the cave". So this kind of fish is inedible.

However, people have a way to eat, and the scaly white turtle has been artificially propagated successfully. Farming is very common in Taian, Shandong, and it is also common in Ankang, Shaanxi.
