Doping overshadows Games
Since the opening ceremony on 4 February, a new global star emerged in the form of 18-year-old freestyle skier Gu, who was born in California but switched to China in 2019 and became the unofficial face of the Games.
There was a new men's figure skating champion in 22-year-old Nathan Chen of the United States, who dethroned two-time Olympic champion Yuzuru Hanyu, in what could be the Japanese legend's final appearance at a Games.
Another iconic figure of winter sports, the American snowboarder Shaun White, will definitely not return to competition of any sort after calling it quits.
The 35-year-old's last event ended agonisingly out of the medals and he was in tears as he bid farewell to snowboarding -- "the love of my life".
There was bitter disappointment for his fellow American, the alpine ski star Mikaela Shiffrin, one of the biggest names at the Games but who went home without a medal.
There were tears from Valieva after it emerged that she had failed a drugs test prior to the Games, catapulting her to the forefront of yet another Russian doping controversy to mar an Olympics and piling intense pressure on the teenager.
In what will go down as a notorious episode in the history of the Winter Olympics, the pre-tournament favourite for singles gold fell several times on the ice in the finals, to audible gasps from the socially distanced crowd of hand-picked spectators.
Her doping case looks certain to drag on in the coming months, long after the Games have packed up. She was allowed to skate in the Chinese capital but has not been cleared of doping.
In a Games first, the skating team medals were not awarded after Valieva played a starring role in propelling the Russians to gold, ahead of the United States and Japan.
The American skaters made an 11th-hour court bid on Saturday to get their hands on their medals before they went home, but the Court of Arbitration for Sport rejected it.
China and its ruling Communist Party will look back on a soft-power success.
Fears about a mass Covid outbreak in the "closed loop" bubble sealing the nearly 3,000 athletes and about 65,000 others never materialised.
Some athletes did though catch the illness and the pandemic was never far away -- Russia and Canada's women ice hockey teams played each other wearing medical masks after the results of their daily PCR tests failed to arrive in time.
Concerns about human rights had dominated the build-up, with the United States leading a diplomatic boycott by its closest allies over China's rights record, especially the fate of the Muslim Uyghur minority in Xinjiang. Their athletes did however compete.
China warned in the fraught lead-up that foreign athletes criticising the authorities could face consequences, but in the end, any protests against the hosts were extremely muted.
There were numerous records -- among them American bobsleigher Elana Meyers Taylor becoming the most decorated Black athlete in the history of the Winter Olympics.
Snowboarder Zoi Sadowski Synnott made history for New Zealand, winning her country's first Winter Games gold; with Gu pocketing two golds, the hosts enjoyed a significant medal bump and finished third in the medals table with nine golds.
That was easily their best performance in the Winter Games, a place ahead of chief geopolitical rival the United States, on eight golds.
For the second Games in a row, Norway topped the medals table, with 16 golds. Germany were second on 12.
