The map shows how the town has changed after the putting up of a hydroelectric power dam between 1990 and 2010. General speaking, the changes illustrate the modernization and improvement of it facilities during the 20 years period.
The most striking alteration is to the river, with a river section next to an ancient structure in 1990 becoming a big lake in 2010, and below it, a hydroelectric dam was built, and an ancient structure was torn down to make room for it. Furthermore, the forest on the top left side, which appeared in 1990, was knocked down, and in 2010, it was just a vacant lot.
Another significant change is the demolition of the irrigated farmlands on the right side, replaced by a hotel and some electronic poles in 2010. In addition, it can be seen the fact that on the lower left side, the rare plants and animals have disappeared, and some electronic poles were constructed. The villages and the mountain were the only things that did not undergo any changes during the 20 years.
