Ye Xingbei found the generational hierarchy between the two families confusing, but Si Duomian's parents didn't think there was anything wrong.
The senior master of their family and Senior Master Gu were of the same generation, and Gu Junzhu was Senior Master Gu's biological son, who called the senior master of their family uncle, so naturally, he should call them brother and sister-in-law.
To them, they were very happy that their daughter could marry Xie Jinfei.
Xie Jinfei's own sister was Gu Junzhu's wife, which was another unexpected joy.
This meant that the Si Family and the Gu Family would become in-laws from now on.
In the future, their daughter's children and Gu Junzhu's children would be related by blood!
Their unborn grandson or granddaughter would have a strong support, giving them a head start in life.
It's not that they were snobbish, but their daughter was excellent by nature, and if there was something good, who would want their daughter to choose the lesser?
