In March, the school organized a spring outing to Mingsha Mountain in a suburban park.

The warm wind blows the people, and the blue sky washes the lungs. In the dazzling sunshine, the sand peaks extend like golden dragons lying across, and look like shining pyramids, of varying sizes and stand in a staggered and orderly sea of ​​sand.

The sand here is different from other places. It is spiritual, and can whisper in a low voice. If you encounter a coincidence, you can hear sings and chants. Ling Xiaowen has heard of it before. The mysterious feeling is restless in his heart. As soon as he stepped into the desert, he couldn't wait to lie down and put his ears on the sand and listen carefully. However, after staying for a full five minutes, he was silent all the time.

He stood up in disappointment and murmured to himself: "It's really a false hearing! Sand is not a human or an animal, so how can he speak out? It's purely a fake story created by a travel company to attract business. Like the 'savages' in Shennongjia, Hebei, the bombing and hype of the major media in almost the country has caused a lot of controversy, but it's actually all 'Cheliuzan'!"

"What are you doing when you are lying down? If you want to take a sand bath, you have to peel off your clothes before you feel comfortable and happy!" Teacher Jin said jokingly.

"Hehe!" Ling Xiaowen smiled awkwardly, and then said seriously, "I want to expose a lie who deceives the world and steals the name!"

"It's like a powerful figure who specializes in doing big things. Tell me, a hero who wants to expose a big lie?" Teacher Jin praised people and was also thorny. When people felt comfortable, they felt an ant crawling in the vest.

"Hahaha!" After hearing Ling Xiaowen's words, Teacher Jin laughed so hard that his tears blurred his lenses. "This is a true scholar's composition and was found to be wrong by illiterate people! A person's IQ fluctuates in a W-shaped shape. I see that your current IQ is at the bottom of W. Haha!"

"I'm going to be wrong for sure?" Ling Xiaowen was puzzled, "Then you, Teacher Jin, can try it out now!"

"Don't be stubborn. If the sand doesn't move, how can it make a sound?" Teacher Jin said, "Go to the top of the mountain to play sand, and then it will 'song'. To be honest, slitting around the sand is not 'song', so it deserves its name to be 'Mingsha Mountain'. It is not a lie, nor a lie."

"Well, so that's it." Ling Xiaowen touched his head and asked again, "Teacher Jin, then tell me, what is the reason for analyzing from a physical perspective?"

"Is it interesting to ask the end of the matter?" Teacher Jin raised his hand and said, "Go and play sand. Yan Ruyu is in the book, and she can play with her brains with ease. The reason is very simple. If you think about it for a while, you can understand the cat and dog. Go, go and play."

Ling Xiaowen climbed to the top of the sand mountain, bought a ticket, and received a wooden board that looked like half a desk. This was the only tool for sand sliding.

Sitting on the wooden board, the person leans back slightly, supports his hands, and puts his feet away, and then he can slide down the slope. The slope is about 60 degrees, and there is friction between the sand and the wooden board, so it will not slide very quickly after starting. The speed seems to be designed by the park, which makes people feel a little nervous but refreshing. In some places, the slope suddenly becomes steep, and the feet can "brake" into the sand, and it can't be stopped, so people can lie down. In some places, the slope is suddenly flat or there are small pits, so you have to go hand and feet like rowing.

The sand flow surging and falling on both sides of the wooden board. They fluctuate up and down, collide left and right, entangled with each other, making a fine and gentle rustling sound, which is sometimes rapid and rough, sometimes delicate and soft, sometimes continuous, sometimes silent and sometimes silent;... Although the rhythm is monotonous, it is endless fun, making people intoxicated by the mysterious murmur of yellow sand. What's even more wonderful is that the sand is mainly tuned, and there are four colors of red, green, white and black, which flashes colorful light in the sun.

After asking many people, Ling Xiaowen quickly realized the truth about the sound of sand: a thousand years ago, quicksand flooded the villages here, so there was a layer of rubble at the bottom. The sound of sand was actually a kind of echo of the rubble being vibrated; but if the sand was wet, especially after the rain, the sand would not sound.

The reason for Shaming is simple and understandable, but the mystery of the nearby Moon Bay made Ling Xiaowen confused.

What makes it wonderful is that its shape remains unchanged, the water is clear forever, and the sand is firmly steadily in the spring. It is nearly 100 meters long from north to south, about 45 meters wide from east to west, and 9 meters deepest, and is curved like a crescent moon, hence the name. A clear spring, with ripples lingering, as blue as jade, never drying up for a thousand years, is a wonder, just like a bright and deep eye in the vast desert, smart and charming.
