Gu Youyou, on her first foray into the palace, seemingly knew no one; who would dispatch a eunuch to remind her of anything?
The Empress? Clearly not possible. If the Empress had wanted to remind her of something, she would have done so before Youyou entered the Renshou Palace, not halfway through the treatment to send a eunuch.
Half an hour passed quickly, and Gu Youyou dismissed the irrelevant eunuch from her mind, once again entering the Empress Dowager's chambers.
The acupuncture session was much quicker this time, completed in the short span of brewing a pot of tea.
The day was getting on, and a curfew would soon be in place within the palace walls; the Empress did not keep her, instead ordering her to be escorted out of the palace as soon as possible.
...
Her visit to the palace went smoothly today, and upon leaving, she even received a gift from the Empress.
