Hearing-impaired family prioritizes needs of their 4-year-old daughter

They named the stall a "Silent Egg Waffle" because they can only communicate with the customers via hand gestures and by typing words on the phone. Sometimes, their daughter comes to help and interacts with customers on behalf of her parents in halting speech.

Though earning a humble income over the years, the couple used all their savings to buy their daughter a set of artificial cochleae and hearing-aids. When asked why they bought the devices only for their daughter, Zhang said, "The devices are far too expensive My wife and I can endure the deafness, but I don't want my daughter to suffer."
