Some Kolkata knowledge:

Kolkata (formerly Calcutta) is home to nearly 4.5 million people, and behind Mumbai and New Delhi, is considered, by GDP, the third-richest Indian city. Kolkata’s economy is buoyed by a duo of trade milestones, as the city has the only river port in India as well as the country’s oldest seaport. Kolkata is also the current home of India’s Bengali film industry. On the flip side, Kolkata is also known for the depths of its poverty, as the late Mother Teresa and her charities continue to work tirelessly to help the city’s poor and disadvantaged.
