'Nothing's easy, everything's possible' in the country

Sam Waldo, co-founder of three-year-old eyewear brand Mantra, said he sees great potential in the Chinese market as more people have grown interest in products with fashionable design and unique social value.

After graduating from Colombia University in 2010, Waldo spent two years teaching English in Yongbao town, Lincang, Southwest China's Yunnan province. He found many children had vision problems but few had proper eyewear.

To figure out a sustainable way of helping them, he founded Mantra in Beijing in 2016 with a promise to donate one pair of glasses to children with poor eyesight on sale of a pair of sunglasses.
