On December 18, Beijing time, the 2021 World Badminton Championships entered the penultimate competition day. In a focus battle in the women's doubles semifinals, the Japanese duo Mayu Matsumoto/Nagahara and Kona were blocked out of the final by the Chinese team Chen Qingchen/Jia Yifan 0-2, and had no chance to defend their titles, and the game was one-sided for most of the time, so that Chinese coach Nakajima Kei, who was the off-court coach of the Japanese team, could only shoot his own head.
As can be seen from the TV turn shot, Nakajima Kei is very helpless to see that the disciples are suppressed in all aspects, shaking his head and patting his head, which makes Chinese fans very relieved. In fact, there are not many former Chinese players who have joined other countries as coaches after retiring, and Chinese fans are generally friendly, but why do they hate Nakajima so much? This starts with the Sino-Japanese showdown in the women's doubles arena of badminton in the recent Olympic cycle. As long as Nakajima Kei serves as a sideline guide and encounters a game in which the dialogue between China and Japan is relatively close or anxious, he will definitely make some moves to interfere with the Chinese team.
The typical case occurred in the 2019 Badminton World Championships Matsutomo Misaki/Reiwa Takahashi and Li Yinhui/Du Yue, which lasted for more than 2 hours, when the two sides of the decider reached a 20-20 draw, and the next one point and two teams continued to play for 87 rounds and were interfered with by Kei Nakajima's shouts, and the referee could only call off the game to let the two sides fight again. The scene was spread on live television, making Chinese fans quite dissatisfied with Kei Nakajima, believing that after he naturalized in Japan, he regarded the Chinese team as an enemy and generally hateful.
This time, seeing That Nakajima Kei was overwhelmed by Jia Yifan/Chen Qingchen on the field because his disciples Matsumoto Mayu/Nagahara and Kona were overwhelmed by Jia Yifan/Chen Qingchen, the fans all shouted "too relieved". With Matsumoto Mayu/Nagahara and Kona eliminated, Lee Yongbo's former partner, who won the Soup Cup with Kuniwa, changed his original name to Ding Qiqing after naturalization in Japan to coach Kei Nakajima, and led the Japanese team to win the women's doubles triple crown at the Badminton World Championships.
