There were many things that Liu Hui Ying hated—— 1) being ignored, 2) being looked down upon and 3) being treated like air and currently, all three things were happening to her at once.
According to what Nanny Gang told her she just needed to serve tea, take the gift that the grand empress dowager has prepared for her and then go back to the safety of her own room where she was free to do whatever the freak she wanted to do but it was as if these blind dogs could not even see her.
She has been standing next to the grand dowager empress with the cup of tea in her hands while the old hag was busy giggling and laughing with that concubine Ju and the jerk who sat next to her. It was a rather humiliating sight as too, the grand dowager empress, the emperor and his beloved Concubine were all sitting on chairs while she alone like the rest of the maids was standing with half of her waist bent as she waited for the old hag to pick up the cup and take a sip.
