BUCT trip to the Great Wall (Gubeikou section)

BUCT (Beijing University of Chemical Technology) organized a trip to the Great Wall for the foreign students. There was no one except our group at the Gubeikou section so it was really not a touristy spot. In 2010, I went to another section where people were selling snacks and bottles of water on the Wall and from where I came down on a toboggan. 

One of our teacher took something like 800 photos. Here are some of them. 

The two women in front + the two women with red hair are our teachers.
