It is only one Mandarin. Other Chinese languages are dialects. Mandarin is standard Chinese. It may happen that people from different area in China speak Mandarin affected by their local accents, which is different from dialect.You can just say they can not speak very good Mandarin. The purpose of Mandarin is making people from diffrent area can communicate with each other easily. You have to understand even Chinese people from diffrent place can barely understand each other in their own dialects.So teachers in China main land are requested to teach in Mandarin.That is why Chinese young poeple can speak much better Mandarin than older Chinese generations.
