On one of Yung's strolls through Central, Hong Kong, he found out that a reputed noodle shop called Sun King Kee was on the verge of closure. He got to know its owners and photographed their last days on the premises - with the same degree of respect and enthusiasm that he would apply while taking pictures of the Russian DJ Marina Deeva and Japanese handpan street busker Taka.

Yung's association with the Community Chest of Hong Kong's Continuing Rehabilitation Centre-SAHK has allowed him to observe physically and mentally challenged locals from close quarters. "My exhibition of their portraits at a spine therapy workshop was a gesture of respect," he says. "Through photography, I can communicate and gain trust in a short period of time. It was difficult to capture them smiling as some cannot control their facial muscles."
