(Diao Chan POV)
Having lived a big part of my life amongst the nobles back at the country of Dong, I could see all the little hidden secrets and motivations of each person within these halls easily.
You can tell a lot about a person's opinion of someone else by how they move, say and even look at the person in question. Not to mention the type of gifts they bring along for you, that is the easiest indicator of their attitude.
For example, that merchant family that just went up was reputed to be one of the top five most influential Houses. The gift they brought along for the princess was a piece of white jade probably worth about a few hundred gold.
