In all over the world, there are more than 100 places where
you can hear the sand sings. In China, there are 6 places, such as Yinken
Resonant Sand Bay in Ordos, Mingsha Shan in Dunhuang as well as Mulei in
Xinjiang. Yinkeng Resonant Sand Bay (briefed as Resonant Sand Bay or
Xiangshawan银肯响沙湾)
is nicknamed as the king.
According to scientists, three geological conditions are
necessary to foster this natural wonder: first, the sand dune must be giant and
steep; second, the leeward side should be crescent-shaped and face the sun;
third, there must be water originating from the foot of this sand dune and
forming a pond. Besides, temperature and moisture in the air also matter.
Hence, sunny days are favorable compared to rainy days.
