List of mainland Chinese schools reopened in Hong Kong

Following the Communist victory at the end of the Chinese Civil War and establishment of the People's Republic of China in 1949, educational institutions from the former Republic of China either relocated to then British-ruled Hong Kong or saw their faculty and staff flee mainland China to escape political repression—such as the 1952 reorganization of higher education in China. These efforts eventually led to the re-establishment of several mainland institutions in Hong Kong.
