The favorite Denmark lost 1-3 to Chinese Taipei due to Axelsen's unexpected loss and missed the semifinals.

- Denmark 1-3 Chinese Taipei
Denmark are the favourites to win the tournament and their three men's singles teams are top-notch, with Axelsen, Antonsen and Gemke being difficult for any country to beat. In men's doubles, they also have World Championship runners-up Astrup/Anders, who have the power to fight with any team. The Chinese Taipei team was in average form in the group stage, with Lin Junyi, Wang Ziwei, and Yang Boxuan/Li Zhehui all like allies. The Danish team was unanimously favored before the game.
In the first men's singles match, Axelsen faced Zhou Tiancheng. The result of this match was very unexpected, Axelsen was not in good form, the world No. 1 lost 1-2 to Zhou Tiancheng, and the Danish team lost a point from the plan. In the second game, due to an unexpected loss of points, Denmark's World Championship runners-up Esstrup/Anders played more tightly and lost 0-2 quickly, closing the Danish team in a desperate situation.
In the third men's singles, Antonsen played against Lin Junyi. Antonsen was under too much pressure in the first game, and he continued to make various mistakes, and lost 14-21. After making timely adjustments, Antonsen regained his attacking touch and won 21-10, 21-14 to earn one point for Denmark.
In the fourth Men's Doubles, Li Zhehui/Yang Boxuan faced Kjaer/Sogaard. Li Zhehui/Yang Boxuan played their recent good form, winning in straight games 23-21, 21-18 to seal the victory for Chinese Taipei.
This is the first time that the Chinese Taipei team has reached the semi-finals of the Thomas Cup, and has made another big breakthrough. Axelsen's recent form has been sluggish, and it will be a bit difficult to win the Olympics.
- Indonesia 3-1 South Korea
In the match between Indonesia and South Korea, Indonesia had a clear advantage in men's singles, and they were unanimously optimistic about their promotion before the game. Although the result was as expected, Ginting and Jonatan were very close in both men's singles, both of which were reversed by opponents winning one game and then winning two games in a row.
In the first game, Ginting played against Quan Yichen, and Quan Yichen took the lead and defeated Ginting 21-14 as soon as he came up. After making timely adjustments, Ginting found the advantage of possession and won two hard-fought 21-16 comebacks. In the second Men's Doubles match, South Korea's world champions Seo Seung-jae/Kang Min-hyuk beat Fikri/Maulana 2-0 to equalize for South Korea.
In the third men's singles match, Jonatan faced Zhao Jianye. The match between the world No. 3 and the world No. 120 almost caused a big upset. Jonatan was stunned by his opponent's attack in the first game and lost the first game 17-21. In the second game, Jonatan found his offensive rhythm at the end of the game and equalized the score at 21-17. In the deciding game, Jonatan was full of firepower and easily won 21-10, with a big score of 2-1 reversal, and the Indonesian team led 2-1.
In the fourth Men's Doubles, the temporary combination of Alfian/Martin played a surprise role. They eased in straight games to defeat Korea's Kim Won-ho/Ki Dong-joo 21-12, 21-13 to seal the win for Indonesia.
So far, the top four have all been released, namely China and Malaysia in the upper half, and Chinese Taipei and Indonesia in the lower half. Asian teams swept the semi-finals, while Denmark once again missed out on the semi-finals.
