What round of badminton competition should I go to Beijing Olympic Games if I want an athlete's autograph?
No matter how many rounds, I don't think the security guard will let anyone near the athletes easily unless the athletes take the initiative to sign autographs for the fans in front of the audience. Watch TV. Players go straight into the players' tunnel after playing the ball. There will be reporters to interview, hold a press conference and go home by car. Do something, maybe there is still a chance, such as bribing field service personnel.
