There's uncertainty and unease amongst the people of Hong Kong.
Tensions are rising following China's decision to pass a controversial national security law, allowing it to punish political uprising more easily.
Hong Kong correspondent Jennifer Creery told Mike Yardly one pro-democracy figure has already fled.
She says others are making contingency plans.
"Many of the popular countries of choice are Taiwan, UK, Canada and Australia, so at the moment there is uncertainty but it is very much still early days."
Creery says those born before the 1997 British handover to China, hold a British National Overseas passport.
She says the UK is offering them the opportunity to work and study in the UK for five years - with a path to citizenship.
"I am sure the UK Government is also sceptical over whether or not 2 million people are just going to uproot their lives and move to the UK, but certainly there is this avenue available for the time being."
