My hometown was upon the highland plateau of Ngari Prefecture,where the Guge Kingdom enjoyed close relations to Chusum,a place far into the deepest reaches of Tibet Autonomous Region.One township within its jurisdiction is Doisig,a name meaning"looking upon to the homeland"(a referenee to Ngari Korsum,about 1,000 kilometers away).The topography here,especially in Chusum Soil Forest(soil piling up hills),is almost identical to the soil forest in Ngari's Zada.
