World Table Tennis Mixed Doubles Championships

China and Japan took everything in the mixed doubles as well.
Korea only managed one bronze medal.
In table tennis, the prize money difference between singles and doubles is about 10 times. Since there are more singles events, it feels like players don't pay much attention to doubles or mixed doubles during the tour.
Doubles wasn't even an official event during the Tokyo and Paris Olympics.
Doubles and mixed doubles require teamwork, but it feels like they only practice their chemistry for major tournaments. Since the prize money for winning on the tour isn't that much, they focus on singles instead.
In other words, if players who are good at singles practice their teamwork and focus, they are also good at doubles.
