Not only the China team, but also the uniforms of other countries should be labeled with advertising trademarks. That's because the interests of sponsors of the Asian Games should be protected, so the trademarks of other businesses can't appear on the field. However, the trademarks of the sponsors of the national team are printed on the uniforms and can only be blocked by paper. It is said that this will also bring less trouble to athletes, because sweat often makes those papers fall off and have to be pasted again to continue the competition.
