Xiaofeng was Ye Cheng's wife, which Yan Junmei certainly knew.
Regarding the marriage between Ye Cheng and Xiaofeng, in principle, she and the Prime Minister agreed, especially since Xiaofeng had given birth to a pair of dragon and phoenix grandchildren for the Gu Family, so she was even less picky.
In her father-in-law's words, their family's Ye Cheng was averse to women, and it was already good enough that he had married a woman who didn't repel him, let alone being choosy.
But now that Ye Cheng was involved in this incident, although Xiaofeng was Ye Cheng's wife, she still didn't want Xiaofeng to suffer and be dragged into it.
Firstly, the matter between the Gu Family and the Xu Family was not a simple romance; it was mixed with too much other information.
