How old is Wu?

Wu Yihan, a 6-year-old deaf-mute girl, couldn't hear her own voice. Her father's "Camel Bell" with gestures and lips touched countless people. Currently studying in Class 2, Sungang Primary School, Luohu, Shenzhen (1). Wu Yihan is deaf and dumb, and it is even harder to speak and sing. While thanking her parents, I found that the child's teacher is also worthy of praise. It is this teacher who cultivated the little girl's singing skills. Society needs everyone to care about the disadvantaged groups.
