Also through to finals day is South Korea’s Lee Yong Dae, who will play in the men’s and mixed doubles title deciders.
Schenk (left), who had not beaten world No. 2 Wang Xin in three previous meetings, turned on the style to win 21-14, 21-16 in only 38 minutes, much to the delight of the partisan crowd.
Showing an aggressive side to her game, Schenk took the initiative to control the tempo of the match and never allowed Wang Xin to dictate terms.
Schenk will now play China’s Li Xuerui, who defeated surprised semi-finalist Gu Juan of Singapore 24-22, 21-14.
Yong Dae, who has won two men’s doubles crowns in Germany and is the defending champion with Jung Jae Sung, has had to work extra hard as he has played eight matches en route to the final.
While he and Jae Sung were expected to reach the final, his mixed partnership with Ha Jung Eun (below), are only the third seeds.
However, the unexpected loss of top seeds Chen Hung Ling-Cheng Wen Hsing earlier in the week cleared the path for them and they took advantage by beating Japan’s Shoji Sato-Shizuka Matsuo 21-23, 21-16, 21-10.
Waiting for them in the final will be former world champions Thomas Laybourn-Kamilla Rytter Juhl, who crushed second seeded Thais Sudket Prapakamol-Saralee Thoungthongkam 21-15, 21-14.
The Danes will be fresher after sailing through all their matches without dropping a game.
Yong Dae-Jae Sung will meet up with Hong Wei-Shen Ye of China after they upset second seeds Ko Sung Hyun-Yoo Yeon Seong 19-21, 23-21, 21-12.
Four-time world champion Lin Dan marched into the men’s singles final when he crushed Tommy Sugiarto 21-10, 21-11, and will meet SEA Games champion Simon Santoso, who defeated Jan O Jorgensen 21-12, 21-13.
In the women’s doubles, defending champion Mizuki Fujii-Reika Kakiiwa were shown the door by Jung Kyung Eun-Kim Ha Na, who won 23-21, 18-21, 21-19.
They will face China’s Huan Xia-Tang Jinhua, who edged teammates Cheng Shu-Pan Pan 17-21, 21-12, 21-17.
