So far, Chinese swimmers have acquitted themselves not well in the 2024 Olympics. Does the more frequent anti-doping checks on Chinese athletes than their counterparts from other countries hurt them? I cannot say.

But, the fact is, the bronze medalist of women 100m butterfly Zhang Yufei had received the check 42 times before the contest, while the gold medalist received none. Are the western swimmers all "clean"? I doubt it.
