In early March, Gulang County, Wuwei City, Gansu Province carried out a spring sand pressing activity. More than 1,000 volunteers dig trenches, draw lines, back grass, bury grass, and fix sand... On the rolling sand dunes, there is no grid-like sand barrier. When there is, it gradually spreads out, like a huge "golden net" tightly locking the flowing sand dunes.
