A Beijing Winter Olympics which saw sporting drama and milestones but was tarnished by a Russian doping scandal ended on Sunday with an uplifting closing ceremony. The Games will be remembered for new stars such as Eileen Gu but also for the doping controversy which engulfed 15-year-old figure skater Kamila Valieva and because they took place inside a vast Covid-secure "bubble". The "Bird's Nest" stadium, which also took centre stage when Beijing hosted the 2008 Summer Games, was the scene for a celebratory, snowflake-themed closing ceremony attended by President Xi Jinping and a socially distanced crowd seated among red lanterns.
