Something to notice about is Japan maybe setting to upstage China diving dominance-8for 8 now! with a stable of women/mens' divers led by 17 year old Tamai-gotta watch the rear view mirror and never underestimate duplicitous China hating Japanese like late Qing."At the moment of victory,tighten your helmet straps" Japanese proverb but possibly ascribed to Chinese-as so much of their culture. If any countries can erode China's dominance in her sporting sphere(TT,badminton,swimming/diving,other precision sports)it's the genetically/ethnically similar Koreans/Japanese with their ironically Chinese like attitude toward diligence/training/selection etc.Perhaps nothing perhaps something to note well and deal with.
