Introduction to Miancheng Senior High School: In April 1952, due to the division of Mianyang and Honghu, Mianyang County was moved north to Xiantao, and Miancheng ended the history of county administration. The office of the County People's Government was changed to Mianyang Junior Normal School, and later to Miocheng Senior High School. After half a century of wind and rain erosion, the Mianyang County Government Office Building still retains its charm.
