As for Ning's business, she has been making adjustments since her decision to pursue freediving seriously, by stepping back from the forefront, where she was often on edge.

Ning's goal for next year is to challenge the Asian record for women's CWT, which is 106 meters, currently held by Japanese athlete Hanako Hirose.

But, she added, freediving is not about competing with others, but with oneself.

"I believe that's the essence of freediving. You can't rush it; you can't see others as your rivals; you can only focus on yourself and your own progress," Ning said. "In some other sports, you might be able to push yourself and see quick results, but in freediving, haste won't get you anywhere. You need patience and the right mindset to succeed."
