CNN News:北京成史上首个举办夏季和冬季奥运会的城市

To date, how many cities have hosted both the summer and winter Olympic games? Five, three, one, or none. No single city has hosted both seasonal Olympics before but Beijing, China is set to become the first next year.

The Chinese capital hosted the Olympic summer games in 2008. It's set to host the 2022 Winter Olympics next February 4th. Looking ahead, the events will return to Paris, France in 2024. Milano Cortina, Italy in 2026, Los Angeles, California in 2028. And the International Olympics Committee just announced yesterday that Brisbane, Australia is the preferred host for the 2032 Summer Olympics. This is a new process for Olympic organizers. They haven't announced the venue for the 2030 Winter games yet and Brisbane bid to host the 2032 games isn't a done deal. The IOC still has to vote on this to make it final. 

But because hosting the Olympics takes years to plan for and because of the uncertainty that still surrounds the 2020 games which were delayed by the coronavirus pandemic, the committees trying to devise a stable and predictable way to determine future host cities.
