Ding Ke jiu jiu

the long version

"Ma Xiaotiao has a mysterious uncle. Other call him 'new human being': he doesn't have a steady home and he travels a lot. He paints his hair colorfully and wears jeans with holes on them. He goes to work in a cafe with his laptop. He likes to watch cartoons and play games as exciting as bungee jumping. Though normally he is a careless man, he is very stubborn about some things. When he drives with his friends and knocks down a guideboard, even though no one sees him, he insists on compensating for it. He is also a firm environmentalist. One time on their hike to a mountain, Ma Xiaotiao sees him pick up water bottles and white plastic bags all the way with his own eyes. This experience strengthens Ma Xiaotiao's admiration for his uncle."--Amazon.com.
