The school was founded by Wong Lan-koon, a grandfather of Elsie Leung.[1]
The police raided the school on 16 October 1967. They seized more than 3,500 inflammatory posters.[2]
On 27 November 1967 two explosions were reported at the school, and a student was seriously injured in the school laboratory. Area residents 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 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, Hon Wah Middle School, Fukien Middle School, and the Mongkok Workers' Children School.[6]
The school was immediately closed by the government following the explosions. 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]
