Why are there alien sites in Delingha, Qinghai? Is it a tourist stunt or have aliens really been here?

A scientific exploration program before CCTV broadcast the mysterious Delingha alien site. This is a desolate place. In the mysterious world of Fiona Fang, which is one kilometer away, there is not a tree and grass, but grotesque rocks everywhere. A mysterious iron pipe was found in a cave. Some people suspect that these mysterious pipes were left by aliens when they visited the earth, and Delingha is the site left by aliens.

Delingha Alien Site is a very desolate place on the shore of Tuosu Lake. In CCTV program reports, we see that there are three side-by-side caves under the Baigong Mountain, two of which have been buried by cliffs, and the sandstone cave preserved now is the largest one. There is a pipe inserted from top to bottom in the cave. The diameter of this pipe is about 30 cm. We can't know how long it is because it is exactly the same as the rock. Around the cave and around Lake Tuosu, there are also many pieces of iron like rusty slag and many pipes.

Many scientists came here for field investigation and research. They made a scientific analysis of the elements contained in the iron pipe and made it very clear through scientific experiments that this tubular object is indeed iron. But there is also a doubt that 8% of the elements in this pipe can't be found. We haven't seen these elements yet. Some people suspect that this pipe comes from aliens, while others say that this pipe comes from the deep sea.

So, what are these mysterious elements? Experts finally came to this conclusion and put forward two possibilities. First, it is suspected that this pipe is a plant fossil; Another suspicion is that the sandstone layer quickly deposited to form a tube.
