Xiao- prefix or -er suffix usually added to a child's name by their close elders (grandparents, parents, uncle, etc) as endearment nickname. Like Gyokuyou calling her daughter Lingli "Xiaoling". Suiren could be mistook the Xiao as family name at first, but Gaoshun gave Xiao nickname with serious tone was such a Dad move..
So Mao means cat (yes her name can be literally translated to Catcat). Which is why she's sometimes drawn with cat-like features. Especially in chibi mode. And the prefix Xiao means little or small. So the nickname Xiaomao is basically calling her a kitten
"Court Lady" is similar to a modern-day government employee. And she must pass the civil service exam (A practice that was first originated in Ancient China) first before becoming one, which is why Jinshi is pushing her to study.
@08:50 ... I think Maomao is trying to stay oblivious concerning Jinshi and ignores the hints deliberately ... because knowing these things might be dangerous and get her into trouble.
Did you hear that the trailer for season 2 dropped? Also I you haven't already, I highly recommend you watch Delicious in Dungeon because it's a very fun and well-written anime. Specifically the dub, because the dub is so good that the original mangaka watches her own show in the dub
6:57 Considering how flat and short Maomao is, I highly doubt it (granted he did jokingly consider it later in the series) as the Emperor prefers women with large "assets"
Water bender faroh edit made me laugh, also pre-fixing a name with xiao is kinda like term of endearment in china, kinda like post-fixing in japan with chan or kun
