The school was founded by Wong Lan-koon, a grandfather of Elsie Leung.[1]
On 16 October 1967, police raided the school and seized more than 3,500 inflammatory posters.[2]
On 27 November 1967, two explosions were reported at the school, with one student seriously injured in the school laboratory. Residents in the area and police alleged that the school was being used as a bomb factory.[3][4] The injured student, 18-year-old Siu Wai-man, lost a part of his left hand. He was charged with possession of explosive substances and sentenced to four years in prison.[5]
The day after the explosions, four other Communist schools were raided by police for suspected bomb-making, namely the Heung To Middle School [zh], Hon Wah Middle School [zh], Fukien Middle School, and the Mongkok Workers' Children School.[6]
Following the explosions, the school was immediately shut down by the government. In mid-1968, the government de-registered the school under the Education Ordinance on the grounds that it had been "willfully used for the unlawful manufacture and storage of dangerous explosive substances".[7][8]
In late-1968, it was reported in the South China Morning Post that all former students of Chung Wah Middle School had transferred to Hon Wah Middle School.[9]
