Beautiful Shot 老何,
A tunnel for the hydroelectric power plant... probably one to send water to the turbines.
Beautiful night capture
It says literally "PRC Jimunai border crossing".
I am running a non-commercial border site called Borderbase.
On http://www.nicolette.dk/borderbase/border.php?c1=75&c2=30 I would be very interested to use your border picture as my missing border crossing photo.
I cannot offer you any money, but would like to simply ask your permission, and I will offcourse credit you the courtesy.

Go west young man!
