This matter ultimately alarmed the Emperor.
After all, the Empress had fainted. As a husband, it would be inappropriate for the Emperor to ignore it.
At that moment, the Emperor, who was used to a life of leisure, was having a discussion with several ministers. His head buzzing, he immediately left his ministers and came to the harem upon hearing of the Empress's condition.
After hearing what had happened, his recently quieted head began buzzing again.
He rubbed his temples, asked weakly, "Has the Empress woken up?"
"Your Majesty, Imperial Physician Dong is performing acupuncture on the Empress," the Eunuch replied, "Master Dong asked me to relay that the Empress simply fainted due to a sudden onslaught of anger and a stagnation of qi and blood. Once she wakes, she'll be alright."
In simpler terms, she was angered to the point of fainting.
