A shadow of those who schemed?

Ji Yu wanted to question Zhai Heng but the latter simply coughed somewhat embarrassingly and then said,  " He just returned from another country which is why he does not know about the customs and the rules of our country, even his majesty has to give way to him sometimes." 

Zhai Heng was not wrong regarding this matter after all Zhai Tianyu indeed have to give way to Liu Hui Ying when the latter was in an unforgiving attitude, even when he was being pushed into a corner like a dead dog, Zhai Tianyu lowered his head and allowed Liu Hui Ying to do what she wanted to do …so who was he to tell Liu Hui Ying to drop her gaze? 

And even if the woman was not dressed as the Queen, she was still the Queen and the ruler of the harem, it did not make sense for her to lower her head in front of an imperial concubine.
