The "county high school phenomenon" of Chinese rural high school education to pursue higher education has attracted much attention from the education field and society. Earlier studies were mostly from the perspective of education and believed that the "county high school education model" was contrary to education's essence because it emphasized test-oriented education and restrained students' nature and should be discarded. However, this model is surprisingly persuasive for rural families, and it is also a reflection of the rural students' desire to achieve upward mobility through education. This paper analyzed the county high school education model's connotation, expounded its operating mechanism, and systematically demonstrated and analyzed the "county high school education model" from multiple angles. It aims to find a way out for the future development of the "county high school education model" to promote education equity between urban and rural areas and the harmonious development of high school education ecology.
