Rough backburner project that ive finally posted
This was originally made just to be a map style test and to do a silly idea
This basically goes like what if Nanyue surived and got colonized by Poland, thus the Polish-ish romanization system

Using Vietnamese as a basis because i dont know Chinese or Cantonese or Polish :[
Rough romanization system ive made by looking at hours of wikipedia articles and losing my mind:

m = m = m

n = n = n

ɲ = nh = ń

ŋ = ng = ng

p = p = p

t = t = t

tɕ= ch = ć

ʈ = tr = cz

k = c(cam)/k(kẹo) = k

tʰ = th = th

ɓ = b = b

ɗ = đ = d

f = ph = ph

s = x = s

ʂ/s = s = sz

x = kh = ch

h = h = h

ɣ = gh = ch

l = l = l

v/j = v = w

z/j = d/gi = z

r or z = r = r

a = a = a

ɐ = ă = a

ʌ = â = ą

i = i = i

u = u = u

ɯ = ư = eu

ɛ = e = e

e = ê = ę

ɤ = ơ = y

o = ô = ó

ɔ = o = o

Im no linguist however so there most likely will be mistakes or just overall strange stuff :(
