Is this line correct? As i born and raised in Dhaka that's why Dhaka has always been a special land for me. Or should i say this in another way?
"I was born and brought up in Dhaka, so it has been a special land for me."
That would be a more accurate sentence.
I would write the sentence as, "As I was born and raised in Dhaka...". You can use them in the same sentence.
