Chittagong is a vast region and city of the same name with a population of three million in Bangladesh with a colossal set of problems. A trip there is not safe, even though airlines offer a bunch of flights :). The country's authorities are now more likely to prevent foreign journalists from entering there, so as not to spoil the image of their state. The population of Bangladesh is almost equal to the population of Russia. The same cannot be said about the area. But they are lucky with the weather. However, if you Google the word Chittagong, most of the links will lead to a very small area on the coast of the Bay of Bengal. This is a place where old ships are broken up.
