This is because the match between Lin Dan and his arch rival, Taufik Hidayat, has been eagerly anticipated. Moreover, his "Backhand Smash" show would be the last one.

The cancellation news was followed by a woman's single from China. Han
Li stated the same reasons with Lin Dan, she chooses to focus on a
national tournament in China.

As a consequence, Han Li will be absent in Singapore Open Super Series
2013 held after DIOSSP 2013. The world's 20th player decision delivers
optimism for Ana Rovita.

Han Li's position will be replaced by Bellatrix Manuputty who is
climbing to the main round from qualification round. Bellatrix will
play against Ratchanok Intanon from Thailand who becomes the 5th
favorite in the main round. Ana Rovita too has entered the
qualification round after being  a reserve player.
