"Impudent!"
The Emperor was furious, "Ling'an, are you determined to go to the East Palace, aren't you?"
"Indeed! I, Ling'an, was born a man of the Crown Prince, and I will die as one!" Princess Ling'an's righteousness and willingness to die rather than submit nearly moved Jiang Ning to applaud her.
During the chaos, Concubine Yu moved to sit next to Jiang Ning and whispered, "Why is Ling'an so resolute? It's only because her grandfather is a meritorious official, and the Emperor must treat her with caution to avoid dampening the spirits of his subordinates."
Jiang Ning laughed and said, "With her making a fuss like this, and the Emperor not punishing her, wouldn't that hurt the feelings of Concubine Shu?"
Despite Concubine Shu's good intentions in trying to persuade her, not only did she show no gratitude, but she also pushed Concubine Shu to the ground.
In a lesser sense, this is ingratitude.
In the larger sense, it's insubordination, gross disrespect.
