Super Junior's Siwon updated his Weibo with a picture of himself standing on the streets of Hong Kong.

He also wrote, "Subway trip in Hong Kong today."  

In the picture, he looks cool and casual in his black-and-red apparel.  The singer and actor normally has a clean-shaven, suave look, but now he shows off some facial hair for a more rugged, manly appearance.

Meanwhile, Siwon is in the midst of filming for Chinese movie 'Helios,' in which he plays a Korean police officer.
