@skinnylatte My paternal grandparents were also from Swatow. My dad (and his siblings) spoke Teochew with them but us grandkids never learned it. Only just random words mixed with Thai here and there, which I’m quickly forgetting. 😕
Sometimes I wish I had known their language better and have the opportunity to learn about the place they came from the way you described it. My cousins and I were even planning a trip to Swatow this year to visit their birthplace, but leaving the US now ended up not being a good idea.
