Chittagong name

Has anybody been to Chittagong recently? My question is, what do the local residents call their own city?

There’s actually a wiki page for that.

Bengali and Chittagonian names

…many people continue to call the city, চাটিগ্রাম (Chatigram) or in the Chittagonian language, চাটিগাঁও (Chatigaon), গাঁও (Gaon) meaning village.
