Are you familiar with the 20 "rules of the game" widely recognized in the badminton world?

1. Whether you know the other players or not, and regardless of their skill level, make a friendly greeting when you meet—don’t come across as overly arrogant.

2. Players should shake hands before and after the match to show mutual respect and a willingness to learn from each other.

3. During the match, if you accidentally hit the ball close to the boundary or out of bounds, politely apologize—don’t secretly rejoice instead.

4. When a badminton shuttlecock flies out of reach, actively go after it—don’t just wait for your opponent to retrieve it.

5. Even after winning, don't become overconfident—there's always more to learn and achieve.

6. Serve only after your opponent is ready—don’t attempt a serve if it would result in a fault.

7. If the ball gets sweaty, proactively wipe it dry before hitting—it’s best not to deliberately wet the ball just to play with it.

8. If you lose the game, accept it gracefully—don’t make up excuses. Remember, winning and losing are both part of the game.

9. Acknowledge and praise your opponent when they make a great shot.

10. When the gap in skill or strength is huge, don’t win by too large a margin—don’t even go for a one-sided victory if it’s possible to avoid it. At the very least, aim for a two-goal difference.

11. When watching the game, please keep your voice down so as not to disturb others playing. And definitely avoid making critical comments or pretending to be an on-court coach by pointing and directing others.

12. While playing, it's best not to casually enter someone else's court. If you need to retrieve a ball, wait until the player has finished their shot before stepping in—and be sure to politely signal your apologies.

13. When practicing, focus on playing well—don’t intentionally disrupt others’ practice just to enjoy yourself. Remember, we’re all here to improve our skills, so let’s respect each other and understand what true practice means.

14. If your opponent hasn’t noticed the net or line call, you should proactively point it out.

15. Don’t rush into shots casually when playing with girls—unless, of course, you’re up against a female powerhouse.

16. When playing sports, arrive on time—ideally 5 minutes early. This also gives you a chance to warm up and get ready.

17. When meeting new golfers joining the group, proactively offer to play or accompany them as a partner.

18. When playing, be serious—don’t let others sense that you’re distracted or unengaged. Nobody enjoys playing with someone like that; even if your skills are top-notch, people will still end up disliking it.

19. During the game, avoid shouting loudly on purpose or using hurtful, disrespectful language.

20. If you’re a more advanced player and there are more people than available tables, take a few turns but then kindly step aside—don’t hog the table without giving others a chance to play.
