I take it for granted that travelers from outside of Hong Kong decrease by almost 100%, because the autonomous city basically banned entry of foreign tourists.
But, judging from the current situation about virus in Taiwan and China, Hong Kong government should turn down that ban on Chinese and Taiwanese.
