Can mainland students go to Hong Kong for senior high school?

You can't go to all the high schools in Hong Kong. According to the policy of Hong Kong, children cannot come to Hong Kong to study in primary schools, junior high schools and senior high schools. Schools in Hong Kong only admit Hong Kong residents or foreigners (Hong Kong International School), and children with mainland household registration cannot apply for kindergartens, primary schools and secondary schools in Hong Kong. Hong Kong, the full name of People's Republic of China (PRC) Special Administrative Region, is located in the south of China, east of the Pearl River Estuary, facing Macau across the sea in the west, Shenzhen in the north and Wanshan Islands in Zhuhai in the south.
