A language survey in China under development for six year was recently published. Interesting reading. It found that 53% of the population speaks the official standard Chinese dialect (Mandarin). This may not sound much for an official language, but when you consider the vast population of China and the huge number of dialects spoken, it is quite a lot. One of the findings of the survey was that many Mandarin speakers use it as their main language in public or at work, but stick to their regional dialect with friends and family.
