Li, the reigning short course world champion in 400m and 800m free, led all the way through the 400m final, lifting the world record 3:53.92 set by Ariarne Titmus of Australia in 2018 Hangzhou worlds.

"I was surprised with my result. I have returned to the pool only for two months since I took a vacation after the FINA World Championships in Budapest, Hungary.
