The shrubs in the Gobi Desert grow tenaciously. The Gobi desert is a geomorphic form on the edge of the desert. The surface is short of water and there are few plants. Only some drought tolerant plants such as red willow and camel thorn grow, and it is often windy. Its formation is mainly due to flood alluvial. When floods occur, especially in mountainous areas, due to the gradual weakening of flood energy, the following geomorphic features are formed in the flood impact area: large rocks are accumulated at the mountain pass nearest to the mountain, and the rocks become smaller outside the mountain in turn.
