Xinhua News Agency, Basel, August 22 (Reporter Wang Zijiang) The World Badminton Championships held its fourth day of competition on the 22nd, and all the top eight in five events were produced. Chen Long miraculously reversed Hong Kong's Ng Ka Long at a critical moment and entered the men's singles quarterfinals. Chen Yufei and Canadian player Li Wenshan also completed three games and narrowly defeated their opponents to advance.

After Chen Long, the third seed, won the first game with 21:13, he encountered a severe challenge in the second game and lost 17:21. At the beginning of the decisive game, Wu Jialang's offensive momentum continued unabated and soon led 11:5. After switching venues, Chen Long seemed to have awakened from a dream, chasing 6 points in a row to tie 11:11. After that, the two tied continuously. At 15:15, Wu Jialang returned the ball and went into the net. Chen Long led all the way from then on, and finally won 21:16. In the next round, he faced Denmark's Antonsen.

Chen Long said after the game: "It was too easy to win the first game. In the second game, I thought I would follow the pace of the game and played a little conservatively, and finally lost the game."

He also said: "I'm happy. Yes, when I fell behind at 5:11, I had no way out, so I went all out to play my best.”
