The adults in the main room were also talking. Cheng Baoguo added a bit more about Erya's family situation.
Her name is Erya because she had a twin sister before her named Daya. Daya was born with health problems, so the sisters were only given childhood nicknames. In the end, Daya passed away when she was three. Her father still has parents and brothers, but unfortunately, none of them are willing to raise her.
With a lack of food and clothes, life is hard. There aren't many people willing to raise someone else's child.
