Looking at the sun, I took out my knife and stuck it in the sand.
When the sun shone down, you could see the shadow of the knife. I used a small stone to hold down the front part of the shadow. After waiting for about ten minutes, the shadow of the knife moved three to four centimeters to the left. I took Dou Sprout's knife and traced it on the small stone.
The position makes a cross.
The shadows of the two knives alternate, and the direction the cross heads are pointing is the west.
I stood up and pointed to the west: "Go there, even if it takes more time to go a little off, you can definitely get there if you go west."
We are definitely still in Tengger. We can only reach Badain Jaran by walking west. The people who return to the customs are just south of Badain Jaran. If we go in the wrong direction and go to the north, the final result will be to keep walking and keep walking until we finally arrive.
Ulan Buhe will all leave Inner Mongolia by then.
After deciding on the direction, everyone moved forward again. At this time, the climate conditions were much worse than those in two or three months. Sandstorms are frequent before winter and after spring every year. According to statistics, there were 46 sandstorms in Ningxia in 2000, and reached 2001 in 2001.
More than 60 times, that is, this year, Ningxia launched the Three-North Shelterbelt System Construction Plan, increased investment in the Ningxia Three-North Shelterbelt Plan, subsidized farmers for tree planting, and reduced the impact of Ningxia's sand sources on Beijing's sand and dust climate.
Everyone went to bed early that night. The wind outside was howling like a ghost. The wind was getting stronger and stronger. The small tent we had set up was swaying from side to side. I didn’t dare to sleep, so I covered my mouth and nose with my clothes.
, ran out and asked everyone to get up and close the tent | don’t blow it away.
"What! What did you say!" Dou Sprout patted his head, covered his mouth and shouted at me.
"Tent! Close the tent!" I shouted at him anxiously.
Dou Sprout heard clearly and hurriedly ran to close the tent.
Liao Xiaomi was blown forward by the wind, and Uncle Liao grabbed him.
I secretly prayed to God that it would stop blowing. It would turn into a sandstorm and it would be over.
I don’t know if they heard my prayers, but the gust of wind lasted for more than half an hour, and gradually became quieter. The wind blew up less and the sand became smaller, and people were finally able to open their eyes.
at this time.
"Don't say anything yet..."
"Listen."
The wind was small, and I suddenly heard a strange voice. The tone was not high. At first, it seemed like a mouse's cry, squeak, and after a few minutes, it seemed like the scream of a frog, 呱.
I thought I had filled my ears with sand and was hallucinating, but when I saw Brother Yu’s surprised look on his face, I knew he must have heard it too.
What kind of land is this? This is a dry and smoking Tengger. There is no water at all. How can there be frogs!
After listening carefully for two minutes, I felt that the sound did not sound like a frog's croaking. If it was a frog's croaking, it would have a rhythm, rising and falling. This is different. This sound does not rise and fall from beginning to end, and always maintains the same sound.
a tone.
The sound came from behind us. Brother Yu was very curious and said to go over and see what was going on.
I said be careful Brother Yu.
Brother Yu waved his hand and said it was okay, he was just curious.
Following the direction of the sound, we followed him towards the back. We walked for less than ten minutes, and the sound became clearer as we walked. Finally, we stopped in front of a large sandbag.
The strange thing is that the croaking sound came from the sandbag.
Sandbags are fine and sand dunes are fine. I saw this place during the day and it didn't seem that big. But now it has become so big. I guess it was blown by the wind.
Dou Sprouts widened his eyes and said, "Is there a nest of frogs living in the sand?"
Brother Yu groaned and asked what was going on. He picked up a stone, threw it casually, and smashed it into the sand dunes.
The stone was thrown in, and after more than ten seconds, the croaking sound changed, and it made a sound similar to a low-pitched erhu, which was very strange.
At this moment, Liao Xiaomi suddenly raised his hand and said: "I know, is this a ringing sand dune? I have heard others say before that there are ringing sand dunes in Tengger."
Later, after my verification, I found that it might really be this kind of ringing sand dune. This was the first time I saw it with my own eyes, and I found it very interesting.
The so-called ringing sand refers to sand that can make sounds. The sound emitted by such sand dunes will change due to the influence of external forces. There are different opinions on the formation of this sound, and scientists have different opinions. It probably means that it is related to the flow of emissions inside the sand.
It was related to static electricity. Later, Jiangxi TV Station's Classic Legend filmed a similar episode of "Sounding Sand," but the result was unclear.
A group of us played there for a long time. When we stepped in, we could hear the sound of airplanes flying by. When we sat in, we could hear a sound like a donkey's braying.
While playing, the fatigue on everyone's faces was wiped away.
When the wind stopped, the surrounding sand dunes gradually became still.
