New consort blatantly taking the materials with her even though MaoMao instructed them that the stuff isn't supposed to leave the classroom. Already looks like she's going to be troublesome.
Tips and tricks from a brothel is probably a really good idea for a royal harem, I guess. Until a harem member gets in trouble for sticking something in the "entry prohibited" region unexpectedly and he is not into it, anyway. At least that seems unlikely (the disliking it part, not the potential girl on dude butt stuff).
It's interesting that she said the new pure consort and her handmaiden wore "southern country" clothing since that style is worn by the Manchu, who are from the northernmost part of China.
