The Xuantian Gate is an extremely unique gateway, where the imperial palace, the inner palace, and the ancestral temple converge. Its significance is comparable to the noble's exclusive Drum Tower for receiving official decrees.
If the noble women knelt there, it was equivalent to announcing to the entire world that Princess Yong Chang was a person without talent or virtue.
This matter had caused an uproar back then, but it was only limited to the inner palace. This was because the Empress Dowager had received the news at that time and quickly sealed off the Xuantian Gate with the late Emperor.
At that time, the late Emperor was not muddle-headed yet. He doted on Little Yaoguang as much as she did and was worried that she would be hurt.
