Of course, Luo Yanyun knew about it. If she didn't know, she wouldn't have said what she said today.
She would never do anything that was against her conscience. Just like how, after Liang Boqin died, she was able to clearly seek protection from the Liang Family and live a good life with her daughter.
But she knew that her daughter did not belong to the Liang Family, and although she did not say so explicitly, she knew in her heart that was the reason why she was able to bear the humiliation and brought her daughter away from the Liang Family.
Even after suffering so much and feeling so much wrong, she still didn't go find anyone from the Liang Family. That's just because Luo Yanyun can't pass the obstacles in her heart.
