Caldwell said she was proud of Xu, whose nickname is Taotao.

"Taotao has been pushing triples for longer than I have, and I respect her wholeheartedly. For her to win the gold medal in her own country is an incredible accomplishment, and it brought tears to my eyes," the US skier said.

Xu said she believes systematic training and keeping in good form brought her the gold medal.

"I've been in good shape for the past four years, so I've given my best to prepare for this moment. Today I only come here to see the result," she said.

"It's going to be a sleepless night for me. I will use every minute to enjoy the win."
