A special "silent" beverage shop in Guiyang, the capital city of China's Guizhou Province went viral overnight. The shop is located by a school for the blind and deaf-mutes in Guiyang City. Apart from the cashier, all the other staff are speech- or hearing-impaired people. Yang Fan, the beverage mixers and cashier, said "what has touched me most is their self-improvement and independent attitude toward life." Although they cannot communicate with the customers by speaking, they wear smiles in their faces all the time.
