Linze county nestles at the foot of the Qilian mountains range and has been a grain production center since ancient times.

Between the Gobi Desert in the north and the Qinghai-Tibet Plateau in the south, this fertile region is nurtured by snow water from the mountains and is ideal for cultivating corn seed.

Indeed, the spread of corn as a major Chinese crop originated from the Hexi Corridor which includes Linze.
