Qingdao is a 'small' city of around 6 - 9 million people (aw, cute), with a reputation for beautiful beaches, relaxed lifestyles, German architecture and 'cleanliness'. The cleaning services provided in the cities I've visited are scarily efficient. People are spitting and throwing stuff on the street all hours of the day, and there's a small army on patrol at all hours just scrubbing it all down. There is a constant ebb and flow of filth and relative clean. I argue that filth prevails, for you cannot unsee some things.
But the cleanliness of Qingdao is an environmental cleanliness. Say 'Qingdao' to a Chinese person when playing a game of word association, and they will say '大气质量很好', (good air quality).
I like this place. I came into a bar and everyone seemed to know I was visiting. Word had gotten around on the Wechat network the foreigners use, and soon I was in the middle of some great Expat event. Most had good things to say about the city. It has mountains and beaches, you can go mountain biking here, you can live here cheaply, you can learn Chinese with ease here. It was starting to sound appealing.
