People react as they watch Siobhan Bernadette Haughey of Hong Kong swim in the women's 100-meter freestyle final at the 2020 Summer Olympics, at a shopping mall in Hong Kong, Friday, July 30, 2021. Haughey, born in Hong Kong four months after the 1997 handover, now has two silver medals from Tokyo, becoming the city’s first-ever multiple medalist. Hong Kong’s haul of treasure from Tokyo, with a gold also won in men’s fencing, outshines the one gold, one silver and one bronze that Hong Kong accumulated through all of its previous Olympic appearances since its 1952 debut at the Helsinki Games.
