Hi @monirulislam, these are such an intriguing post. Nice clear pictures, yet I got a lot of question, if you don't mind answering.

In which country does this route located?
What are they use for (is it for trade? connection between cities? vacational spot?)?
What are those people doing in the background?

I hope you can write more details to give me better grasp of situation, it would be more interesting read, imo.
