Niu Niu, a six-year-old girl, has become a good helper in a silent foot spa (足疗馆). The owner of the foot spa and all of the workers can't hear. And the girl helps them to communicate with the customers.
Niu Niu is the daughter of the foot spa owner Hu Yong, who lost his hearing because of a high fever in his childhood. This made it difficult for him to get a job. After finishing training in a foot spa, Hu started his own business in Chengdu in 2019. Peng Feng, the mother, who is also deaf, works together with her husband at the shop.
Though their shop is small, it is popular with customers because of the couple's good skills. The foot spa is usually busy in the evening, when Niu Niu comes home from school and helps her parents. Niu Niu helps her parents in her sweet child voice and with rich body language. She is very funny and always makes customers laugh happily.
"She is always cheerful, active and outgoing," said one of the customers.
"Dad taught me to work hard," Niu Niu said. In her opinion, her parents are like superheroes who look after the family and her. "My parents are different from other people, but they are the best for me," she added.
