Liu Li explained that the maidservant had complained several times to her, although the latter didn't dare to say too much about her mistress' matter, Liu Li got the gist of it. They both knew that Liu Li was working for Madam Wang as well, hence she dared to say a thing or two to her.
Madam Wang's personal maidservant had been serving her even before Madam Wang had gotten married and she already disliked the younger sister that Madam Wang had doted on the most. The younger sister seemed to be sly and have a hidden motive to get closer to Madam Wang!
The maidservant could see the greediness inside Madam Wang's younger sister's eyes a few times, besides, she kept deliberately talking about Jiu Lan in front of Madam Wang --- even though she knew that it was a taboo. After all, she also knew that Madam Wang had always been jealous of the person that had been gone for a long time. Was it really neccessary to bring her up every now and then in their conversation?
