I was flipping through the Xi'an dialect volume of the Great Dictionary of Modern Chinese Dialects.
On p. 206 I came across:
and on p. 207 there is:
There is the /pf/ initial and the aspirated consonant /pf‘/.
I'm quite curious to see what these sound like, especially since /pf/ seems like a topolectical equivalent of zh in MSM and /pf‘/ one of ch.
What do the /pf/ & /pfʰ/ initials sound like in Central Plains Mandarin?
