"The most important thing is to see strength in unity. Only by better uniting and cohesion can our cause not be afraid of high mountains and roads, and move forward without hindrance." Representative Liu Faying, deputy principal of Huaping Primary School in Longzhouping Town, Changyang Tujia Autonomous County, Hubei Province, said, In recent years, with the joint efforts of all walks of life, the construction of teachers in remote areas has achieved gratifying results, and the quality and professional ability of the teachers have been continuously improved. It is recommended to further increase policy support for rural teachers in remote areas and strengthen the allocation of excellent teachers. With the help of science and technology, we will achieve universal education and help the balanced development of education to produce more fruits.
