China is seen as a monolith, sometimes even among the Chinese. Something that came up is 几多 vs 多少 (how much) in modern China. Someone from Beijing will say 几多 is only used in Cantonese speaking areas and in old texts since it's such an archaic way of asking "how much" that's been preserved in the far south, despite the fact that I hear it on a daily basis here in Wuhan, it's like 40/60 for 几多/多少. Also 饮 (to drink, eat or enjoy in general) vs 吃 (eat), 喝 (drink) or 抽 (inhale). 饮 is very rare for my dialect of Mandarin and only really paired with 料 to make 饮料 (drinking mixture/concoction, refers to soft drinks or other non alcoholic beverages or fruit juices), but I think other locations will still use the old verb.
