Kids, go and learn Hakka by watching this!
The Hakka sung in the parody resemble Fui Chew Hakka. I grew up exposed to two dialects of Hakka from my paternal and maternal families. My dad has a Fui Chew background while my mom speak Tai Poo Hakka.
I can tell apart Fui Chew and Tai Poo Hakka by pronunciation differences in certain words - 到 is pronounced as "dou" in Tai Poo Hakka and "dao" in Fui Chew Hakka; 好 as "hou" in Tai Poo and "hao" in Fui Chew.
