What do the /pf/ & /pfʰ/ initials sound like in Central Plains Mandarin?
I live near Xi'an and I can confirm /pf/ &amp; /pfʰ/ are accurate. It's literally p + f. It's like pronouncing /p/ while having your teeth on the lips for /f/, so when your mouth opens, it's a natural /f/.
edit: I think it should be mentioned this is Xi'an-only. Xi'an dialect belongs to 中原官话关中片 (Central Plains Mandarin in the region of Guanzhong), but other dialects in the same subcategory doesn't have /pf/, let alone the broader category Central Plains Mandarin.
