Hong Kong has eased social distancing measures after the local transmission of COVID-19 was contained. 

Entertainment venues in the city have been allowed to reopen. Most of them were shuttered in early April when Hong Kong suffered a second wave of infections. 

When the outbreak first started in Hong Kong, people rushed to buy face masks. As the virus can't be eliminated in a short period of time, are there any long-term public health measures the Hong Kong government is planning to take?
