Can the sand in the desert sing?

In the desert near Crescent Spring in Dunhuang, Gansu, there is a Mingsha Mountain, and the sand on the mountain will "sing". If you slide down the leeward slope from the top of Mingsha Mountain, there will be bursts of music behind you to send you down the mountain.

In dry and sunny weather, the leeward slope of the snowy hill will also produce the same music, some like running water, some like Songtao waterfall, some like crying, and some "ding-dong ding-dong" sound. Although its music is not as beautiful and pleasing to the ear as when players play music works, it is also very strange.

Music will be produced not only on dry snowdrifts, but also on ordinary snow. On a cold and windless day, it is very lively and interesting to watch the snow pattering under your feet. Sitting on the sleigh, listening to the sound of sliding iron below, sometimes strong and sometimes weak, "rustling", like a silkworm chewing mulberry leaves, is also interesting.
