Sanyuan Dongjiao Middle School is a modern high school with high standards and specifications established by the county party committee and government 1999. It began to enroll students in 2000. At that time, there were five high schools in Sanyuan County, among which Xiyang, Anle and Dong Jiao had relatively weak teachers, a small scale of running schools, and the quality of education and teaching could not be effectively improved, which restricted the balanced development of high school education in the county. This problem has been highly valued by the leaders of the county party Committee and county government who have been paying attention to education. In order to speed up the modernization of education, build a well-known brand of Sanyuan Education, and run a satisfactory high school education for the people, in August 2005, leaders of Sanyuan County Party Committee, county people's congress, county government and CPPCC "four major teams" gathered in Dong Jiao Middle School to carefully plan the blueprint for the development of Sanyuan High School education. After on-the-spot investigation, repeated research and full demonstration, the county party Committee and government put forward a scientific decision to concentrate resources and take the road of high-quality high school education development. It is decided to optimize and integrate the existing high school education resources in Sanyuan County, and merge the former Anle High School and Xiyang High School into Dong Jiao Middle School with good hardware conditions and superior geographical location, so that the county will eventually form a "three-legged" trend of Nanjiao Middle School, Beicheng Middle School and Dong Jiao Middle School. The integration of resources has brought new development opportunities to eastern suburb middle schools. After nearly three years of unremitting efforts, "Dong Jiaoren" has developed the school into a high-standard modern high school, and initially demonstrated its strong development potential and advantages.
