In a post-match interview, He Shibei said: "Recently, my results have been very close to the world record, and everyone around me has told me that I can do it. But I try not to think about it, just focus on the game plan and think about how to swim better. Even though it was a pretty good game, it felt like it could be improved a little bit more. 2021 is the best year I've had so far, but I hope it's not the best year of my life because I still hope that more good things will happen in the future.
