Actually, Bai Ruozhu doesn't really care about surnames. A name is but a code, but this era doesn't allow such nonchalance. Your surname determines which clan's genealogical record you belong to, which ancestral hall you worship at, and if you are a boy, the recommendation for the Imperial Examination you will need from your clan.
"Dad, what kind of question is that? Chang Sheng was the one who came to marry into our family, if the child doesn't take the Bai surname what surname will he take?" Bai Yihong frowned, he didn't expect the old man to pick on this issue.
The grandpa gave him a cold glance, "You have the nerve to say that, when you let someone marry into our family, did you ask me, the head of the family? I didn't agree to it, so how can the child enter the Bai Family's ancestral hall?"
Bai Ruozhu looked at Grandpa in shock, he is a scholar but he promised before, doesn't he feel shameful to not keep his words now?
