The Empress Dowager gave the Princess a long lecture about tradition, respect, and her duties as a new wife.
However, all these lessons were useless if Liu Li doesn't apologize to the Old Marquis and the Madame. They would never let her in the Jing An mansion again if she doesn't humble herself.
Determined to fix things, the Empress Dowager sent someone for Xia You. She wanted to mediate between Liu Li and the Xia family so they could all put this behind them. However, a servant came back and reported that Xia You would be unable to come as she was tending to the Old Marquis.
The Empress Dowager then asked for Chunfeng but was told that he too would be unable to come because he couldn't leave his father's side.
She wasn't stupid. She knew that the Xia family was doing this to teach Liu Li a lesson. However, since she had no urgent and credible reason to drag them to the palace, she couldn't do anything.
