Lee Chong Wei will meet Chinese second seed Chen Long in the final of the Hong Kong Open after the Malaysian world number one breezed past Japan's Kenichi Tago on Saturday.
The top-seed and Olympic silver medallist saw off sixth seeded Tago 21-19, 21-15 in 45 minutes, with the Malaysian smashing his way to the $350,000 Badminton World Federation Super Series tournament final.
Lee will face Chen after the latter beat unseeded Tommy Sugiarto from Indonesia 21-18, 21-10.
In the women's draw, China's top seed Wang Yihan overcame Germany's Juliane Schenk 21-8, 19-21, 21-15, to set up an all-Chinese final after her compatriot Li Xuerui defeated another Chinese player Wang Ling 21-12, 21-13.
In the men's doubles China's second seed Cai Yun and Fu Haifeng fended off a fierce challenge from compatriots Liu Xiaolong and Qiu Zihan 18-21, 21-17, 21-16 in a 62-minute encounter.
They will meet Malaysia's top pair Koo Kien Keat and Tan Boon Heong after they advanced to the finals beating Taipei's unseeded Lee Sheng-mu and Tsai Chia-hsin 22-20, 21-13.
In the women's doubles, it will be another all-Chinese finals between top seed Tian Qing and Zhao Yunlei and the controversial duo Wang Xiaoli and Yu Yang, who were disqualified during this summer's Olympic Games for playing to lose.
Yu, who along with Wang, raised eyebrows when she won last week's China Open, after apparently announcing her retirement a day after her expulsion in August.
But Yu on Tuesday denied she was quitting and said she now wants to focus on the sport.
