Besides Aunt Fuya from Third Grandpa and Third Grandma's family, there's also the family of her own aunt, Gu Daya.
Elder Gu and Granny Gu wanted to sell Gu Daya off, but she refused and ran away with a peddler. Over the years, she had never returned to her parents' home, only sending a letter and a tael of silver to Gu Dashan once, saying she was doing well.
Gu Dashan had always been worried and had once wanted to visit Gu Daya's marital home, but kept getting delayed because of earning a living.
During the drought and flight from famine, upon passing through Mingshan County where Gu Daya had married into, Gu Dashan took the opportunity to inquire about Gu Daya's family while resting, but unfortunately, found nothing.
