Be social like these insects

This is the picture of group of insects grouped in a colony. It was very interesting to see all the small insects colonizing themselves and getting close to each other forming a very smooth surface. When the move due to disturbances, individual insects can be seen but in some minutes they again come close together to form the colony. I don't know exact scientific or common name of this animal but if you know, let all know. The insect look like ants but I didn't check the number of legs to confirm whether they are ants or spider. They are lying in cemented wall.

Juju dhau - King of yogurt

Bhaktapur is also famous for Juju dhau - Newari name for King of curd or yogurt. It is called dhai in Nepali. Earlier, the market demand of curd was fulfilled by the same brand name but there are many brands now. In the name of 'Juju dhau', locals also produce curd and market in the name of juju dhau. Like the tradition of making curd and selling in market, the tradition of carrying in shoulder - 'kharpan' is still practiced. You can see a man carrying curd (don't know whether it is juju dhau or other dhau) and looking for the buyers.
