2019 BWF Tour, Malaysia Open. She was the first to advance to the semi-finals of mixed doubles, and then Taiwanese player Tai Tzu Ying swept Thailand's No. 1 Intanon 2:0 and took the lead in advancing to the semi-finals of women's singles.

2019 Badminton World Tour, Malaysian Open, Super 750 level event, today’s quarter-finals, the national badminton mixed doubles combination Zheng Siwei / Huang Yaqiong took the lead and swept the Thai combination Amitabh/Ni in two games Di Peng was the first to advance to the semi-finals of mixed doubles, and then Taiwanese player Dai Tzu Ying swept Thailand's first sister Ratchanok Intanon 22:0 (21-19, 21-13) and was the first to advance to the semi-finals of women's singles!

Taiwanese player Tai Tzu-ying is currently ranked number one in the world in women's singles. She is a technical player who uses fake moves to look real. She often "plays" players such as world champion Ma Lin, Nozomi Okuhara, , etc. without daring to predict. Judging starts early. Although Tai Tzu Ying has not yet won the title of world champion, fans have already called her the "queen of the ball"!

In the 2018 season, Dai Ziying had a fruitful year. She won eight tournaments and scored more than 100,000 points. The period of occupying the first place in the world is about to surpass the record of Li Xuerui . Dai Ziying’s opponent today is Thailand’s No. 1 sister. Intanon, the "genius girl" in the badminton world, did not have outstanding results in the 2018 season, but she defeated Tai Tzu Ying to win the women's singles championship in the 2019 Malaysian Masters. Her record against Tai Tzu Ying is 13 wins and 10 losses. Intanon can be said to be Tai Tzu Ying's strongest opponent in his career!

Tai Tzu Ying has not won a single title in this year's competition. She only won the women's singles runner-up in the All England Championship. This time in the Malaysian Open, Tai Tzu Ying seems to be ready to win the championship. In the first game, she was defeated by Inda. After a few fake moves, Danon began to focus more on the game. When the score was behind, he stepped up his attack and scored several points in a row. He won the first game with a two-point lead. In the second game, Danon took advantage of the situation and attacked. With multiple opportunities and Intanon's consecutive mistakes, Tai Tzu Ying easily won the second game and swept her strongest opponent in two games!

In the semi-finals, Dai Ziying may have a rematch with the first Chinese feather sister Chen Yufei . I wish Chen Yufei can defeat Dai Ziying again in the Malaysian Open after defeating her in the All England!
