Nguyen Thuy Linh's opponent in the women's singles quarter-finals of the 2023 China Masters badminton tournament is Kim Ga-eun (Korea, world No. 15). Against a player who was rated higher, the Vietnamese athlete had an impressive start when she continuously led in the first half of the first set. Thuy Linh was the one who reached the 11-point mark first and brought the first set into a break.

Back on the court, the Vietnamese player had taken a 14-10 lead. However, Thuy Linh suddenly ran out of steam afterwards. The 1997-born athlete could no longer maintain her accuracy in finishing shots, as the ball often missed the net and went out of court. Kim Ga-eun took advantage of Thuy Linh's mistake to score 4 points in a row, tying the score at 14-14.

In the final points of the first set, the two players played a tug-of-war, continuously surpassing each other in points. In the decisive moment, the Korean female player showed her bravery and won the first set with a score of 21-19.

Winning the first set, the Korean world No. 15 had a big mental advantage. The second set also witnessed Kim Ga-eun's complete superiority over Nguyen Thuy Linh. The 26-year-old Vietnamese athlete could only draw points with her opponent in the early stages. But since the score was 5-5, Kim Ga-eun accelerated strongly and won 21-10 in the second set. Thereby, Kim Ga-eun won the final match with a score of 2-0 and entered the semi-finals of the 2023 China Masters international badminton tournament.

This was a very successful tournament for Nguyen Thuy Linh. The Vietnamese female tennis player had very impressive victories in the outer rounds, against opponents who were rated higher. She defeated Line Hojmark Kjærsfeldt (Denmark, ranked 20th in the world) and especially won spectacularly against world ranked 5th player Carolina Marin (Spain, won 1 gold medal at the 2016 Brazil Olympics; 3 times world champion in 2014, 2015, 2018; 6 times European champion).
