A group of college students in China went on a cross-country bike ride after graduation. While riding through a small town they came upon a small stray dog. They fed the dog and the dog followed them for the rest of the cross-country journey.

All 1,110 miles of it. Up and down four-mountains for 20 days the dog followed. At the end one of the cyclists adopted the dog.

His new name is Xiao Sa. Ii's pronounced She-Oh-Sa. I would guess that means dog that follows. Meet Xiao Sa.
