What's the difference between Cantonese in Guangzhou and Cantonese in Hong Kong?

Cantonese of Guangzhou people will be influenced by Cantonese of Hong Kong people, especially before CCTV entered Guangdong, Cantonese in Guangzhou was basically the same as Cantonese in Hong Kong. Because I don't know who said Guangzhou was undefended, the development of Guangzhou dialect has been greatly affected since the people who said winter melon came down. For example, people in Guangzhou used to call buses like Hong Kong, but now they call them buses, which are far away. Another example is eraser, which is called "eraser" in Guangzhou and "eraser" in Hong Kong. Some pronunciations will be different, such as death. Hong Kong people can speak "XI" (Cantonese pronunciation) and Guangzhou people can speak "sei" (English pronunciation). etc ......

However, to correct it, the Cantonese spoken by the anchor of Guangzhou Radio Station is not completely authentic. For example, Zheng Da, I found that he mispronounced several times while watching TV, but it was actually a local accent. If you want to hear authentic Cantonese, you should go around the old city, such as Dawa.
