Madam Xiao did not think that there was anything wrong with her being in contact with the Du family.
She and Li Chenglan got to know each other in France. She affectionately addressed her as 'Sister Lan'. Later on, when they got closer, the two of them were on a first-name basis. Counting the years, they had known each other for 40 years now.
Their relationship was good and often contacted each other, so they were naturally much closer.
Commander Xia's expression darkened when he heard that she was going to look for the Du family. He had to remind her, "You know the relationship between the Xia and Du families. Although Ah Yuan doesn't acknowledge you, you just said so yourself that your bloodline with Ah Yuan can't be severed.
"It's your choice to be friends. I won't interfere, but I hope you won't do anything to hurt your only family—the Du family. You have to know your limits."
