This season, the national doubles lineup has been adjusted, especially the men's doubles, with the retirement of Li Junhui, Han Chengkai and other players, the coaching team has re-paired the men's doubles, world champion Liu Yuchen and Ou Xuanyi played, and the two veterans Liu Cheng and Zhang Nan once again joined hands to participate in the game. In the previous German Open, Liu Yuchen and Ou Xuanyi reached the final for the first time and finally won the runner-up. In this Korea Masters, the two advanced to the final again, they lost two consecutive sets 14-21, 16-21, and lost to the comeback Korean veteran Kim Ki-jong / Kim Sha Lang, who once again missed the championship.
In the past two years, the national feathers have won the championship in various sports, and also won the mixed doubles and women's singles championships at the Tokyo Olympic Games, except for the men's doubles, which has never broken the championship drought. Since the 2020 Malaysia Masters, the men's doubles have reached the final six times, all of which have lost and won the runner-up. The 2020 Malaysia Masters Li Junhui/Liu Yuchen, the 2020 Thailand Masters Liu Cheng/Huang Kaixiang, the 2020 Tokyo Olympics Li Junhui/Liu Yuchen, the 2021 World Championships Ho Ji Ting/Tan Qiang, and this year's Thailand Open, Korea Masters Ou Xuanyi/Liu Yuchen, they all reached the final and final and did not qualify for the final.
After Li Junhui retired, Liu Yuchen and Ou Xuanyi formed a new combination, and the two competitions in which the two partnered reached the final and had unlimited potential. After the game, Liu Yuchen also said that his thoughts and actions in the final were still lacking in success, but he would not blindly rush to succeed, he saw the progress in the game, and when the mind was more mature and the people were more stable, they would come naturally, and it would always come. Liu Yuchen also specially thanked his teammate Zhang Nan and has been encouraging and supporting himself and Ou Xuanyi.
In the men's doubles final, Zhang Nan made a cameo appearance as a coach to Ou Xuanyi/Liu Yuchen as an off-court coach, and he sat on the sidelines with a domineering look in his eyes. Zhang Nan won the mixed doubles title with Zhao Yunlei at the 2012 London Olympics, Fu Haifeng at the Rio 2016 Olympics and Liu Cheng at the 2017 World Championships.
Before Ou Xuanyi partnered with Liu Yuchen, his partner was Zhang Nan, the two failed to impact the Tokyo Olympic Games, and in the Paris Olympic cycle, Zhang Nan re-partnered with Liu Cheng, and Ou Xuanyi was partnered with Liu Yuchen. However, after Zhang Nan and Liu Cheng were paired, the two races they participated in were stopped in the first round, and the two still needed time to constantly grind back to their former state.
