黄土高原

As the subsistence farming of loess plateau with frequent natural disasters such as drought and geographically is far away from the economic center. In recent years, it is very common in that country"s countryside that the labors earn life outside their hometown which leaves the problem of "the children-staying-in-local " education gradually serious. I profess in a countryside high school in Tongwei county and know that place"s situation thoroughly thus I gain the first-hand materials.

作为全国有名的贫困县，在经济上属于黄土高原自然农业经济，干旱等自然灾害高频发生，在地理上远离经济中心，近年来，当地农村劳动力外出务工的现象非常普遍，"留守子女"的受教育问题日益突出，本人任教于通渭县的一所农村完全中学，熟悉当地情况，能够获取第一手资料。
