From the Valley of Medicine Masters?

As the best courtyard in Chuxiu Inn, it was much bigger than any of the courtyards that Ren Jiapei had in the Ren family household. Within, there were fifteen rooms: five master bedrooms and ten rooms for the servants.

The five master bedrooms were lined up in the middle of the courtyard, while the servant rooms were distributed in the two corners closer to the door. Ten servant girls stayed in the rooms.

"Welcome to the Chuxiu Inn." As Zhou Donghuang and the rest walked into the courtyard, the ten servant girls stood in two rows and bowed in greeting. They then rushed forward to grab the bags from Fu and Aunt Mei. A few of them stepped forward together to take the black iron spear from Fu.

Clearly, they could tell that it was a spear made entirely of black iron and was immensely heavy. If not, they would not have come forward to take it together. This detail did not go unnoticed by Zhou Donghuang. "These servant girls have good judgement."
