Cantonese, known as Cantonese and Guangfu dialect in Guangdong and vernacular in Guangxi [33], is a kind of tonal language, belonging to Sino-Tibetan Chinese dialect. It is the mother tongue of Guangfu people in Guangdong [38] and Cantonese people in Guangxi. Widely used in central and western Guangdong, southeastern Guangxi, Hong Kong, Macao and some countries or regions in South China and Southeast Asia, as well as overseas Chinese communities. There are some sayings about the origin of Cantonese, such as the elegant words of the Central Plains in the north and the Chu language of Chu State. From the Han Dynasty to the Tang and Song Dynasties, the Han nationality in the Central Plains moved to Lingnan continuously, which promoted the development and stereotypes of Cantonese. Cantonese has not changed much since Yuan, Ming and Qing Dynasties. It is lazy for men to send lam, and lam is sent in authentic Cantonese areas.
