World No. 1 Wang out of China Open, in tears
Wang, last year's World Badminton Federation (BWF) Super Series Finals champion, blamed her lack of patience for the 18-21, 19-21 loss at the hands of the young Thai Thursday.
"I was too impatient on the court today, which led to numerous faults," said Wang, who turned around to wipe tears off her face before being interviewed.

"I really hope that I can find a way-out as soon as possible," she said. "I need to improve both techniques and mindset."
Meanwhile, Inthanon Ratchanok, who earned her fame as the youngest-ever world junior champion when she won the BWF World Junior Championship title at the age of 14, was elated about her victory.
"I'm very happy because I beat the No.1 right now. I feel more confident about myself because if this time I can beat China, then I can try to achieve more in the future," the 16-year-old Ratchanok said through an interpreter.
