SMALL MATTERS GET BIGGER
It was rare for the Empress Dowager to call her son by his courtesy name. Just as the woman used to call Wu Jinhai by his birth name, the woman usually did the same to Wu Shun.
However, even though only a few weeks had passed, many things had changed, including the way the Empress Dowager greeted the two men she previously appreciated with all her heart. Perhaps it was her disappointment that changed her attitude towards the two men, but she no longer greeted her son with the slightest intimacy, and she did not even want to mention her grandson's name when talking to her son.
Wu Shun was not blind, nor was he stupid, and he noticed the obvious changes in his mother. Even if he had more authority in the empire compared to his mother, he was still a filial son who didn't want to hurt his mother's feelings, and that was why he couldn't ask his mother to stop questioning him.
