Bian Zhongyun (Chinese: 卞仲耘; 19 June 1916 – 5 August 1966) was a deputy principal at the Beijing Normal University Female Middle School (now Experimental High School Attached to Beijing Normal University).

Song Binbin and another student, Liu Jin, put up the first poster denouncing teachers at the school.

Song has stated that although she was one of the leading Red Guards in the school during the unrest, she did not participate in the killing of Bian Zhongyun.

For several decades, witnesses, including Wang and Song, refused to openly name the students who were involved in the killing as they were politically connected individuals.

Professor Wang Youqin, former Experimental High School Attached to Beijing Normal University student, was among the first scholars to study the Red August of Beijing, the origin of the "Red Terror" of the Chinese Cultural Revolution, during which students attacked and even killed their teachers.

It claims that Song, a student leader involved in the Red Guards in the school, was sent to the United States to study on government sponsorship and invited back to Beijing Normal University as a prominent alumna.
