While Cantonese is the dominant language, it's important to note that:
* Mandarin is the official language of China and is widely understood by Cantonese people.
* English is also becoming increasingly prevalent, especially in urban areas and among younger generations.
* Depending on where they live, Cantonese people might also speak other regional languages or dialects.
It's also worth mentioning that "Cantonese people" is a broad term. It encompasses people from the Guangdong province and Guangxi Zhuang Autonomous Region of China, as well as various communities around the world. This means there might be variations in language usage depending on the specific region and the individual's background.
