Mandarin and Cantonese are the two most commonly spoken Chinese dialects. So let's now look at the differences:

- informal spoken Cantonese has 9 tones, while Mandarin has only four (or five, depending on how you count them)
- Cantonese and Mandarin don't have the same vocabulary and grammar
- Mandarin is more spoken in Mainland China, Taiwan, and Singapore, while Cantonese, on the other hand, is more common in Hong Kong and Guangdong
- Mandarin uses simplified Chinese characters while Cantonese uses traditional Chinese characters
- Cantonese uses the Jyutping romanization system while Mandarin uses Pinyin
