first fishermen settled here in the 1930s，it was an unexpected land covered with moss and trees.No one knows exactly what moved the sand to this place，but experts believe it was caused either by the massive fishing that damaged the seabed vegetation，allowing the sand to rise up and be swept to shore，or by the deforestation carried out by the local population decades ago.

　　The sand dunes now constantly migrate up and down the coast by the westerly wind，and can completely bury houses in Shoyna in a single night.Locals have grown accustomed to the shifting sands and waking up to sunlight going only through the top part of their windows，but always leave their front doors open so they don't get blocked in.Local meteorologist Natasha told English Russia that she now uses a manhole cut into the roof of her house as a door，after getting sick of constantly having to dig the building out of the sand."It's very comfortable，" she says."You get out right on the ground and go wherever you want."

　　Shoyna has just one bulldozer to help the people dig out their homes after a windy night，whose driver is Sasha.It takes ten hours to uncover a house completely，and since one hour of work costs roughly 70，few people can afford his services.The Russian government only subsidizes(补助) 40 hours a month，which is far from enough.What's more，there aren't enough hours in a day to help all those in need."I dig one house out，and the others are mad at me，" he says.

　　Apart from having seen many of the houses sink beneath the sand，locals have also developed physiological problems from constantly having to walk on uneven sand，according to the local doctor.There are no roads or railroads connecting Shoyna to the rest of the world，so the only ways in and out of the village are by sea or air.Despite their struggles with the sand and isolation(孤立) from the world，locals are reportedly very proud of their off­the­grid settlement and very generous and friendly to visitors，inviting visitors into their homes for traditional seafood feasts，despite lack of fish in the sea.

　　Now many scientists come to Shoyna in order to study and understand the phenomenon of sand dune migration and how to stop it.
