Thanks for those pics. Kinda making me homesick.
My family actually used to live in a neighbourhood in central Rangoon around Mogul Street, and as the name suggests it is an area mostly populated by people of Indian ancestry. Rangoon was basically an Indian town during the days of the British Raj, and even today the percentage of people of Indian descent in Rangoon would be much much higher than the national figure.
One thing I do notice about Burmese Indians is that many of them have become fully assimilated in the country such that they have adopted Burmese names, can only speak Burmese and wear Burmese clothes. This really is a great contrast to Indians in other parts of SE Asia in particular Singapore and Malaysia where Indians still stand out as a separate ethnic and linguistic community.
