While Hong Kong's government workers were clearing its battered roads - Kevin Cheung saw an opportunity.
He rushed over and salvaged 36 umbrellas from the refuse - left by the city's intense protests.
The parts of which he now saves - and turns into musical instruments.
At his workshop, Cheung uses the umbrella's ribs as materials for thumb pianos.
An instrument played by plucking tuned metal tines attached to a small wooden board.
His aim was to make a version that could play "Glory to Hong Kong." A song that's become a rallying cry for democratic freedoms in the semi-autonomous Chinese hub.
(SOUNDBITE) (English) UPCYCLING PRODUCT DESIGNER KEVIN CHEUNG, SAYING: "I feel powerless and I feel like I should do more.
But other than joining the fight, I feel that's my talent to reuse this material to tell the story for them and to everybody who is not noticed what's happening in Hong Kong.
So I think it's quite heavy because I feel sorry for them and also the city.
So I think this kind of little thing I can contribute to the movement." He says he has sold 45 pianos and made over $10,000 so far.
Which he has donated to two organizations supporting the protester's welfare.
Cheung also teaches people how to make the pianos.
And is one of many people drawing inspiration for art from the movement.
