The 2023 Badminton World Championships have determined all five individual championships. Chinese women's doubles team Chen Chenchen/Jia Yifan defeated Indonesian pair Lahayu/Ramadanti 2-0, crowned the "Four Champions" of the World Championships, and achieved three consecutive championships. However, this is also the only gold medal that Guoyu has won at this year's World Championships. In the mixed doubles final, Zheng Siwei/Huang Yaqiong, who had the chance to win the fourth championship at the World Championships, suffered a three game defeat to the South Korean duo Xu Chengzai/Cai Youding, regretfully missing out on the new history of winning the "four crown" of the duo. In the end, Guoyu finished with 1 gold, 1 silver, and 4 bronze.

Who would have thought that the South Korean team was the biggest winner of this year's World Championships - the entire team won 3 gold and 1 bronze medals, and An Xiying easily defeated the Spanish star Marin to crown the first post-2000s champion in the history of the World Championships; Xu Chengzai, who doubles in both events, has become the first male athlete since the 21st century to achieve a championship in both events at a single World Championships.

The stunning performance of the South Korean team also sounded the alarm for Guoyu: the upcoming Asian Games will undoubtedly make the South Korean team Guoyu's biggest opponent. Faced with their advantages in women's singles and men's doubles, as well as their impact in mixed doubles, Guoyu must enrich his tactical play and seek breakthroughs. Looking ahead to next year's Paris Olympics, it is even more necessary for Guoyu to use more scientific and advanced methods for physical training and reserves, after all, physical fitness is the foundation of everything.

Guo Yu: Great Achievements in Women's Doubles, Small Regrets in Mixed Doubles

In the women's doubles final, Chen Chenchen/Jia Yifan, who had the mission of defending their title, striving for three consecutive championships, and winning their fourth championship, defeated the Indonesian pair Lahayu/Siti 21-16 and 21-12, winning the gold medal for the Chinese team at this year's World Championships. The "Fan Chen" group not only became the women's doubles group with the most gold medals in World Championships in history, but also achieved an unprecedented three consecutive World Championships, winning three World Championships in one Olympic cycle.

Looking back at the history of the four championships, Chen Chenchen said that the feeling of winning this championship is similar to the first time he won it in Glasgow in 2017, and it feels like his first time reaching the top. As for the driving force behind creating history, Jia Yifan said, "At the Tokyo Olympics, we were unable to reach the highest podium. Since then, we have been holding back a strong desire to win a championship in every competition. Because we know what it feels like to win a championship, and what it feels like not to win a championship. That's why we have been eager time and time again, and have a higher fighting spirit with each stop."
