There are five events in London Olympic Games: men's singles, women's singles, men's doubles, women's doubles and mixed doubles. The total number of participants is 172, with 86 men and 86 women.
London Olympic Games implemented a "slimming plan" for badminton competition, and the full seats of three doubles events were reduced from three to two. At the same time, the entry threshold of two singles events was raised. Only when at least three people enter the top four in the world on May 3 this year can they get three full seats.
China finally got a full seat of 12 for the first time in Olympic history, but due to the "slimming plan", the seats of China in London Olympic Games were less than those in Beijing Olympic Games.
Unlike the previous Olympic Games, which only had knockout rounds, the London Olympic Games adopted a new competition system, that is, the first group match was followed by knockout rounds. Among them, the men's and women's singles group matches are divided into 16 groups, with a maximum of 4 people in each group, and the first place in the group reaches the quarterfinals. The three doubles events are divided into four groups, with a maximum of four pairs in each group. The top two in the group advanced to the quarter-finals and crossed out.
