The Qingdao dialect is the local dialect of the city of Qingdao and nearby towns, in China's Shandong Province.
The basic, though not at all universal rule for converting Putonghua to the Qingdao dialect in the pinyin system is that a Mandarin 1 tone will become a Qingdao 3, 2 becomes a 4, 3 becomes 1 and 4 remains four.
The Qingdao dialect's 1 tone (Mandarin's 3) also has a drawl to it.
Different neighbourhoods, from Zhanshan to Xinjiazhuang to Maidao, will have their own variations.
Qingdao's urban dialect words originated between the 1940s and the 1960s.
