Chinese pair Li Xuerui and Sun Yu booked their place in the final of the Bonny China Masters following their semi-final wins on Saturday.
Top seed Xuerui was first up on the courts of the Xincheng Gymnasium in the Olympic Sports Center, edging Porntip Buranaprasertsuk 21-14, 22-20.
Xuerui breezed through the opening game with little problems, but the second game was a different story.
At 19-13 up, Xuerui looked to have the game all sewn up, but the Thai player battled back to make 20-all before Xuerui won the final two points.
Yu defeated fellow countryman Chen Yufei 23-21, 21-14, surviving a close battle in the opening game before dominating the second.
While Xuerui leads their head-to-head 5-1, Sun has been in fine form as she is yet to drop a game at the tournament.
