上山下乡运动
In 1978, the students came back after the 'Down to the Countryside Movement'. To accommodate them, Qinghua Fuzhong Erbu (清华附中二部), a new school later renamed to Qinghua Er Fuzhong (Second Zhongxue affiliated to Tsinghua) was founded, offering only middle school grades. In 1984, the middle school section from Qinghua Fuzhong was relocated into Qinghua Er Fuzhong, making Qinghua Fuzhong a dedicated high school.
