It was a pretty cheap barber shop at the street corner where my parents live. A girl, looks like from contryside, served as my barber and gave me a perfect service (including wash my head twice and constantly ask me if I'm satisfied with her work). When it was done, the whole price is 20RMB --- damn cheap! The cheapest barber I can find in US is $30, and it doesn't do washing.

As a habit, I added 5 RMB as the tip to her. She was absolutely shocked, can't believe and didn't know if she should accept it for a moment:-) With my insist, she received the tips, and was so grateful that she kept saying "Thank you! Da Ge" I feel good at that time. Those are hard working people, and they deserve my payback.
