In the 4th matchday of the Badminton World Championships, the national doubles three-line setback, in the women's doubles, men's doubles and mixed doubles events suffered defeats, all of which were bitter defeats in three sets: the young women's doubles team Xia Yuting / Liu Xuanxuan lost 1-2 (11-21/ 21-9 / 13-21) to India's Pang Napa /Ski, Olympic champion Zhang Nan and the young Ou Xuanyi partnered in the men's doubles, facing Malaysia's strong rival Su Weiyi / Xie Dingfeng in 3 sets 1-2 (18-21 / 22-20/16-21) Missed the round of 16, mixed doubles duo Guo Xinwa / Zhang Shuxian 1-2 (16-21 / 21-17 / 14-21) lost to Denmark's Kristiansen / Bor, so that the mixed doubles 4 pairs were completely destroyed.
Women's doubles was once the ace event for the Chinese badminton team to rush to the top of the world, starting from the 1996 Atlanta Olympic Games, five consecutive Olympic women's doubles champions belonged to the national feather, until 2016 by Japan's Reiwa Takahashi / Matsutomo Misaki to break the momentum of consecutive championships, Tokyo Olympic championship battle Chen Qingchen / Jia Yifan unfortunately defeated Indonesia's famous Lahayu / Polly. This year's World Championships Chen Qingchen / Jia Yifan becomes the number one hope of Guoyu Rushing Gold.
The young combination Xia Yuting / Liu Xuanxuan encountered Indian veteran Pang Napa /Ski, the performance of both sides in the first two sets was big ups and downs, the difference in each set was more than 10 points, after coming to the decider, the Indian combination with more experience in international competitions played more stable, the tactical execution was clear, and the national youngster made consecutive mistakes in the 9-9 score, and finally collapsed and failed to qualify for the women's doubles round of 16.
In the men's doubles competition, the veteran Zhang Nan and his new partner Ou Xuanyi played, Zhang Nan won the men's doubles championship at the World Championships, when partnered with Liu Cheng, in order to promote the growth of young men's doubles players, the two led a small team member to start competing in the international arena, before Liu Cheng / Huang Kaixiang has lost out, this game Zhang Nan / Ou Xuanyi to meet the Malaysian strong file Su Weiyi / Xie Dingfeng, although the opponent is the first-class combination of the international badminton men's doubles in the past two years, but the new combination of national featherweight is not afraid of strong hands, Especially in the 2nd set, 2 points were difficult to pull back, but unfortunately Zhang Nan appeared in the decider to the limit of physical fitness, in the face of fast-paced attack, and finally regretted the loss, so that the Chinese men's doubles in the round of 16 only Tan Qiang / He Jiting a pair of pairs, they will encounter Malaysia's Su Weiyi / Xie Dingfeng on the road to the top 8.
The mixed doubles match was greatly reduced with the defending champion Huang Yaqiong /Zheng Siwei upsetting out, and the young players could basically do tenacious resistance in the face of first-class masters but were always frustrated in the decider. Guo Xinwa / Zhang Shuxian in the match against the 12th seed Danish combination Christiansen / Bor, after the first two sets of the game to 1-1, the decisive game is inexperienced, coupled with nervous pressure, and finally won the game by the opponent, so that the mixed doubles army was completely destroyed, and the champion was missed in advance.
It is a pity that Guo Yu's three doubles defeats, all of them have fought hard with the opponent for 3 rounds, played to the decider because of the lack of physical fitness of the veterans or the lack of experience of the young players, have given the opponent the opportunity, in addition to the men's doubles This game is obviously inferior, in the women's doubles and mixed doubles both have the opportunity to win, young players after such a big competition experience, should be summarized as soon as possible to grow.
