Cao Yuan originally had an older brother and a younger sister, but neither were raised to adulthood, so he appeared to be an only child, although that wasn't the case.
As for his in-laws, his father-in-law was from another place and his mother-in-law was a local. His father-in-law's relatives rarely interacted, but the relatives on his mother-in-law's side still kept in touch, so visits during the New Year were necessary, and that's how Xiao Xiao received her New Year's money.
"Then you tell Mom, how will you handle this money?"
"I want to save it, Mom. Can you get me a savings book? I want to deposit it in the bank, so in the future, I can use it for my education."
"Don't you want pretty clothes or good food?"
"Doesn't Mom already buy those for me? So I don't need to use my money, right?"
