How will the national security law change education in Hong Kong?

A Hong Kong educator was banned for life from teaching in the city after he was accused of making separatist remarks in a classroom. Hong Kong Chief Executive Carrie Lam said the government decided to pull the teacher’s licence after a “thorough probe”. But an education system insider told the South China Morning Post that the teacher’s comments were part of life-education classes meant to help pupils understand freedom of speech. China’s central government has blamed schools for helping to foment opposition to the ruling Communist Party. One opposition lawmaker in Hong Kong says the government’s moves will further hinder speech freedoms and have a negative impact on the education system in the city.
