These two guys live right across the border on the Indian side. Their blood relatives live in the town that they are overlooking in the video. But due to the highest ridge line that form the boundary of both countries, neither side can look into the other country except by deliberately climbing the highest peaks nearby, or cross the border.
(Abridged translation below, they speak pidgin Hindi)
Cameraman:
This guy is Techi Hemi, who is extremely happy to fulfill his lifetime wish to see Chinese development which we have always heard and also seen on internet.
This is Nayu, over there is Tungdo village, over there Ganggar airport ( actually it's Nyingchi airport).
The Chinese have made the place shine with development, roads and bridges everywhere even the hillside are covered with electricity towers.
( Then he prods Techi Hemu to say something in their own local language).
Techi Hemu: we came here of our own account. They have developed everything and everywhere here etc etc
