Silence gives way to sound with cochlear implants

China's first recipient of a cochlear implant to restore hearing in 1995 remembers the experience as an adventure that was "totally worth it".

Lu Feng lost his hearing as a side-effect of drug use at age 21 and lived in silence for 10 years before getting the implant. Three months after the surgery, his hearing returned. He now owns an IT company.

"I am lucky. Most Chinese cannot land one," he said.
