Perhaps this could be why Mama Yen didn't like him that much. Yue Yan was sure that the old Yanyan's intelligence was seen as a threat to Mama Yen.
He now knows that that old may is not his mother, but he couldn't tell whether Dada Gu is his father or not.
But from the way that he was treated up until the day Mama Yen had pushed him into the valley, Yue Yan could tell that Chen Yan was an important figure to them.
There was no way that they would've treated him well and let him in charge of the family if he was really an outsider or just a useless, abandoned child.
There is something more that the old Yanyan might know about his supposed family. But all that would be answered in due time.
As Yue made his way to the ceremetary, he plucked some nice Calla lily and Chrysanthemums flowers and arranged them beautifully into three bouquets.
