Many of the students struggle with learning Mandarin.
Most students have their own local dialect from the specific town or locale they are from.
These are variations of Cantonese in the GuangDong area. This particular dialect takes its name from the GuangZhou, which use to be called Canton and is the provincial center. It is clear that language differences throughout China are very pronounced and that different dialects are difficult to adjust to. This is probably the result of geographical constraints that mark China separating provinces from one another in many ways. If one comes from Beijing or Shanghai, their language is technically Chinese but will be said if very different ways.
