BUILDING IRRIGATION WORKS IN TIBET

Medog is the only county in China with no highway access. The government invested heavily in the construction of such highways, but the efforts failed because of frequent landslides and mud-rock flows. To date, the goods and materials needed by the county still need to be transported by being carried on shoulders over snowy mountains, passing through the places with frequent landslide and primitive woods, and threading a narrow way along cliffs.
