It's nothing. Hong Kong will not cooperate with the mainland during the Olympic Games.

Because the Olympic Games can be held in the capacity of a region (for example, there will also be a British country or an American country), and Hong Kong returns to China, the China government grants it the privilege to participate in the Olympic Games alone, which is one of the conditions for Hong Kong's return, just like allowing Taiwan Province Province to have an army to return to China, which is a political means.
