The three-time Asian champion, who has suffered a catalogue of injuries in the last 24 months, knows he will face an uphill task against the reigning world, Olympic and Asian champion from China.
A former Olympic medallist, Sony now has a chance to get back into the limelight against arguably the greatest badminton player of his generation.
The unseeded Sony booked his ticket to the final four when he defeated India’s Sourabh Varma 21-6, 21-8 in just 29 minutes.
Lin Dan, who has been far from his best in this Grand Prix Gold tournament, reached the semis by edging Taipei’s Chun Shih Kuei 22-20, 21-17.
The other semi-finals will be two up and coming Chinese youngsters, Yuekun Chen and Gao Huan.
The women’s semi-finals will see top India’s Saina Nehwal taking on third seed Porntip Buranaprasertsuk of Thailand (left), while former world champion Wang Lin meets second seed and three-time world junior champion Ratchanok Inthanon.
