Many badminton players who decided to retired after Olympics make BWF did some policies. However. After BWF received the resignation letter from the badminton association in every country of the players, BWF then removed their name in the entry of badminton player in BWF.
Before, some badminton single players removed from BWF rank. Some of them include Wang Yihan, Wang Shixian, Wang Zhengming, and some others name. Now, their name is not listed again in BWF rank or in BWF badminton player entry.
After some weeks, now this is the time for doubles player removed from BWF Rank. Some of them are Lee Yong Dae/Yoo Yeo Seong, Kim Gi Jung/Kim Sa Rang, Zhang Nan/Zhao Yunlei, Ko Sung Hyun/Shin Baek Cheol, Yu Yang/Tang Yuanting, and Tian Qing/Zhao Yunlei.
Now, there is no their retired badminton players name within BWF rank. Even though those badminton players still have points and stayed in top 10 ranks, BWF officially removed their name. It might because BWF had received the resignation letter from their country.
Lee Yong Dae/Yoo Yeon Seong name removed from the first rank men doubles. Lee Yong Dae retired and Yoo Yeon Seong played with the other players. The second rank men doubles, Goh V Shem/Tan Wee Kiong climbed to the first rank men doubles for the first time in their career.
Yu Yang/Tang Yuanting actually still stayed in the second rank women doubles after Misaki Matsutomo/Ayaka Takahashi. But, their name also removed from BWF rank. Jung Kyung Eun/Shin Seung Chan climbed from the third rank to the 2nd rank women doubles.
Many badminton players rank climbed, because of the removal rank from the retired badminton players.
Congratulation for Goh V Shem/Tan Wee Kiong as the top rank men doubles now.
