In the match played at the Palais des Sports, Zii Jia, who was the top seed in the tournament, was sent packing by the unseeded shuttler 21-23, 7-21 in just 39 minutes, Bernama reported.
The win also helped Nguyen break his duck with Zii Jia, having lost the last three times they met on the court.

It was Zii Jia’s first tournament since he injured his ankle at the BWF World Tour Finals in Hangzhou, China, last December.
