A day after beating Denmark’s Jan O Jorgensen in the preliminary stages, Chong Wei enjoyed an easier 21-14, 21-16 win on Saturday.
The three-time champion, from 2008-2010, had his nose in front in the first game and easily took it 21-14.
In the second game, Jorgensen had a brief dispute with the instant review system and lost focus, allowing Chong Wei to surge 11-3 ahead.
But a momentary lapse of concentration by the two-time Olympic silver medallist allowed the Dane to slash the deficit to 14-11.
Chong Wei, however, decided not to waste any more time and stepped up a gear to complete his win in 42 minutes.
“On Friday it seemed tougher because both of us had already qualified for the semi-finals and I didn’t go all out,” said Chong Wei.
“Today, with a place in the final at stake, I was a lot more focused.
“But it’s worrying that I started to slow down in the second game. That’s something I need to improve on.”
Chong Wei also pointed out that while it was great to have instant reviews, there was still much room for improvement.
“There was a situation in which Jorgensen didn’t get the call. I thought it was out though,” said 31-year-old Chong Wei.
“While the new review system is good and fair, I believe that it can still be improved.
“For a start, showing the review on the big screen ... just like in tennis, would be good,” added Chong Wei, who will take on Indonesian Tommy Sugiarto in the final.
Tommy, the son of Indonesian legend Icuk, prevailed after stunning second seed Kenichi Tago of Japan 21-14, 19-21, 21-5.
Meanwhile, mixed pair Chan Peng Soon-Goh Liu Ying's campaign came to an end after they were beaten...again, by world No.1 Zhang Nan-Zhao Yunlei.
