It contains nine tones and six modes, retains many of the characteristics of ancient Chinese, has a well-developed script, can be expressed entirely in Chinese characters (Cantonese characters), and is the only Chinese language other than Mandarin that has been independently studied in foreign universities.

Cantonese is the mother tongue of the Guangfu people and an important carrier of Guangfu culture. Cantonese is written as "Cantonese" in English and "広東語" in Japanese, and is generally referred to as "Cantonese". Cantonese is not only the carrier of Lingnan culture, but also the link between the Chinese diaspora, and an important bridge connecting Guangdong with Hong Kong, Macao and Southeast Asian diaspora. In this sense, there is almost no other dialect in the country that can match the influence of Cantonese.

Cantonese has preserved a lot of ancient vocabulary and grammar. For example, the Cantonese word "li shi" (利市) has been recorded in the I Ching (易经), which means "less capital, more profit". According to the "Yi Miscellaneous Notes", "Ying Shang Li Shi, Ying Da Li Things", businessman sent called Li Shi, to take the meaning of favorable to do anything.
