When Nan Yu came downstairs from the bedroom, she happened to run into Nanny Wang returning from Huo Juanyan's place.
Nanny Wang was humming a lively tune, her hands holding a box as she approached Nan Yu.
"Young Madam, I just encountered someone at the door delivering a local express package for you, so I brought it in for you," she said.
Nan Yu took the box from her hands and saw the address and the sender's initials, NZY, on it.
She recognized them as the initials for "Nan Zhuoyuan," put together from the first letters of each word.
She said to Nanny Wang, "Nanny Wang, thank you."
Nanny Wang, in a good mood, replied, "Young Madam, you're welcome; it was no trouble at all."
Then, her curiosity piqued, she looked at the box.
"Young Madam, what's inside?"
Nan Yu immediately opened the box, "It's an invitation to a banquet."
Upon removing the first layer, a red invitation was revealed, with the most prominent inscription being "Miss Nan."
