Eileen Gu needed a pep talk from her mother midway through the freeski slopestyle final to win her second medal of the Games.
The Californian-born Chinese sensation added silver to the gold she won in last week's Big Air, overcoming a shaky start to finish 0.33 points behind winner Mathilde Gremaud of Switzerland.
The 18-year-old said her mother Gu Yan could see that she "wasn't fully in the zone" after her first run and urged her to "pretend you have no more chances" on her second of three attempts.
Gu ended up taking a hefty backwards tumble on her second run but she got there in the end, claiming silver on her final attempt ahead of Estonian favorite Kelly Sildaru.
"I guess my imagination's not that good so it came down to the real third run, and I did it," said Gu, munching on a local steamed bun as she spoke to reporters. "For that, I'm so, so proud of myself."
Gu was in third place after the first run but she slipped off a rail on her second run to leave her eighth.
She will have another shot at a medal in freeski halfpipe, with the qualification round taking place tomorrow and the final on Friday.
She said the "trifecta" of three freestyle skiing medals at the Games had "always been my goal" and she kept the dream alive with a gutsy performance in slopestyle.
Gu was particularly looking forward to the halfpipe because her grandmother was arriving to cheer her on. "She's never watched me compete before, so hopefully I can put on a good show for her," she said.
Gu has described her grandmother, who was a basketball player at university, as a "fiercely confident" woman, who instilled in her a deeply competitive streak.
Gu said she was going to make a little time yesterday to celebrate China's traditional Lantern Festival, which is the end of the Lunar New Year celebration.
