On Haidian Island in Haikou we have our own beach which is about 20 min. walk from where I am living. It is not the most beautiful beach on Hainan nor the cleanest but people like to come out to watch the waves, play in the water or search for mussels between the stones on low tide beside the beach.
During Spring Festival the beach was even crowded with people who came out to enjoy the sunshine.
One day suddenly these huge sand vacuum cleaners arrived on the beach and started sucking away the sand.
Since this day it became clear why they built this long contrete wall in the sea because the machines are working nearly night and day sucking away the sand spraying it over the wall into the huge basin they cut from the sea with the wall. Soon this basin will be filled with sand and they can start building more appartment houses on the newly recovered land.
