First, I had grown up being taught that my hometown is the place I was born and raised.
But according to some people I've met, Chinese regard one's hometown based on their father's hometown, not their birthplace/growing up place. So eventhough I was born and raised in Perak and my dad is from Johor, my "true hometown" would be Johor.

Second, my mum's family speaks Cantonese, dad's side speaks Hokkien. However, I took to speaking Cantonese instead of Hokkien and our family does not practice any Hokkien traditions.
According to the same people I've met, me and my siblings are considered Hokkien simply because our father is a Hokkien
