I never lived in Penang but I spent a lot of time there. I lived many years in KL but Penang feels more like a place that I ‘know’. Perhaps linguistic: the language of the streets of Penang is Hokkien and Malay and English, not Cantonese and Malay and English.
Hokkien is a language I speak quite well, understand extremely well, and more importantly it is the only language my mother seems to emote in, so it feels much closer for me than the Cantonese of KL.
