Jiangbei, Jiangnan, Jianghai — these three regions generally boast affluent households. Paired with Lu Country's traditional custom of pampering daughters, women from these areas tend to be quite independent and opinionated. Or to quote a Liu surnamed netizen from the North who wishes to remain anonymous, each one is a "real piece of work."
Of course, it's quite normal for Mr. Liu to make such biased and unfair judgments due to his own personal grudges and systematic regional discrimination against women from the Wu-speaking areas.
Having had extensive interactions with Su Yunjin, Chen Lingyun, and his sister Yan Jing, Yan Yu considered himself quite qualified to speak on this matter. To call them "real pieces of work" was exaggerated; a more accurate description would be "full of ideas."
Of course, having dealt with Chen Lingyun in his previous life, Secretary Su of the Gravity Envoys could hardly be considered troublesome.
