The quarterfinals of the 2023 Badminton World Championships ended in Copenhagen, Denmark in the early morning of the 26th. Guangdong star Liang Weikeng and his partner Wang Chang defeated the Indonesian duo Fikri/Morana to advance to the semifinals. They booked a medal in advance for their first appearance at the World Championships. The world's number one men's singles player Asalson (Anselon) was unexpectedly eliminated, with Indian player Prannoy defeating him.

Liang Weikeng/Wang Chang narrowly won three games the day before, and today they also played three games against their opponents, with scores of 21-18, 15-21, and 21-14, respectively. However, the two stated that their emotions were not as tense as the previous day, and the situation on the field was not as critical as the previous day. "It feels good," said Liang Weikeng. "Indonesia's combination has a relatively fast speed and often ends the battle in the first few shots, which is their advantage." Wang Chang said that winning back the previous day was so difficult, so this game doesn't seem so difficult. "The key points and key games must be adjusted, and momentum will play a very important role." Although the two have already achieved the semi-finals goal set before the game, they said that the game still needs to be played one game at a time, Advance towards the champion.

With the elimination of Shi Yuqi, the men's singles team of Guoyu was completely defeated. Shi Yuqi was defeated 0-2 by the famous Japanese general Naraoka Takayoshi, and was eliminated from the quarterfinals. However, the biggest upset of the day was still Asalsen's elimination. Asalsen, the champion of the Tokyo Olympics and last year's World Championships, has been in excellent form this year, winning 37 out of 42 matches and firmly occupying the world's number one position.

After the game, Asalsen said he couldn't remember how many mistakes he made and had been playing in an uncomfortable pace. "However, this is life, and I need to learn from it and see how to move forward. I really enjoy playing at home, the super good atmosphere and support, so I am disappointed with my performance and have disappointed Danish fans."

Among the women's singles semifinals, only Dai Ziying from Taipei, China, who often dominates various events this year, fell behind in the BIG4. Chen Yufei defeated Wang Zhiyi in two sets, while South Korean An Xiying and Japanese star Sai Yamaguchi both advanced smoothly. Dai Ziying lost to Danish star Marin. In the semi-finals, Chen Yufei will face An Xiying and Ma Lin will face Shan Kouqian.
