Mandarin is the official language of China and the largest of the Chinese dialect groups.
Mandarin, and most other Chinese dialects, is a tonal language, which means it relies on pitch to convey the meaning of a word.
On top of that, Mandarin is the most widely spoken language in the world with almost a billion native speakers worldwide.
However, the language is not as hard to learn as many think, as it does not rely much on modified verbs, linking words or prepositions.
