The Yang family dispersed upon the Imperial Concubine's order, and Yang Jingxiu indeed should have gone to greet other guests, such as the Wang Family—it was improper to stay here all the time. In fact, Yang Jingxiu still had not understood why the Imperial Concubine would come. He had just asked a series of roundabout questions, and Huangfu Qing evasively talked around them, revealing no true intentions.
Yang Jingxiu was completely baffled and treated it as some sort of hint from the Emperor—could it be that the Emperor wanted to send some signals to the world?
It might be helpful to discuss this with Wang Daozhong; perhaps some insights could be gleaned.
Yang Jingxiu left some observant maids and servants while withdrawing the men, giving the Imperial Concubine ample comfortable space before he took his leave.
