When Zhang Yongsheng and his wife Zhan Jingwen, both of whom have hearing disabilities, considered whether or not to bear a child, they conducted a gene test and the result suggested that their offspring would not develop the same impairment. Yet, unfortunately, the baby girl was diagnosed with a hearing disorder.

From then on, the couple has worked hard to save for medical treatment and an artificial cochlea for their daughter.

The couple tried several small businesses, such as selling toys and popcorn. In June 2022, the family has opened a stall selling egg waffles at a night market of Sifangping shopping mall in Changsha, Central China's Hunan province.
