Born in Yichun, a city in Northeast China's Heilongjiang province, Gao started skating at the age of 8. After impressing in the junior ranks, he soon emerged as a strong contender on the international stage, claiming 500m gold at the Asian Winter Games in February 2017. Ten months later at a World Cup meet in the United States, he set a new national record (34.34) over the distance.

After his breakthrough at the 2018 Pyeongchang Olympics, Gao continued his upward curve, winning the 500m at a World Cup meet in Poland in November 2021, and finishing second in Calgary, Canada, later that season.

On Saturday, Gao raced in the seventh of the 15 pairs, and shot to the top of the rankings with his Olympic record, which the likes of defending champion Lorentzen and reigning world champion Laurent Dubreuil of Canada could not beat.

Gao said the main difference from his triumphant Beijing run compared to his bronze-medal finish in Pyeongchang was his mentality.

"This time I skated on home ice and I felt both nervous and excited, which is good for competing in important races," Gao said.
