Play hard during the game and compliment your opponent's excellent plays.

Avoid playing in a way that mocks your opponent.

Do not mention that you are not feeling well today.

Do not belittle your opponent's play or say they are weak based on your own standards (this behavior is characteristic of inexperienced players).

Do not argue about points that are not net calls.

Follow someone when retrieving the ball (at least partway).

Do not win five games in a row without allowing your opponent a chance.

Avoid giving your opponent too many difficult serves when it’s not a match.

Do not serve weak serves as if you are letting your opponent to win.

Accept defeat gracefully when you lose (do not make faces when you lose).

Do not taunt your opponent when you win.

Wear appropriate sportswear and table tennis shoes while playing.

When there is a significant rating difference, lower-ranked players should politely ask for a reasonable handicap.

Avoid distracting movements, such as wildly swinging a racket.

Do not hit hard during warm-ups or suddenly give a backhand without warning.

During the match, do not talk to others nearby, and avoid looking around (do not play while watching people passing by).

When teaching inexperienced players, think about what they want to learn rather than unilaterally imposing your style.

Do not quit after only one game if it’s not enjoyable, or stop playing when you are about to lose against a less experienced player.

 Do not frown when your partner makes a mistake in doubles, and avoid playing solo without considering your partner.

 Participate in external tournaments to improve skills and foster camaraderie, not just play in the table tennis hall.

Do not only play with experienced players for your improvement, and don’t cling to them for too long (ask after about 15 minutes if you can continue playing).
