Before liberation, Hong Kong was influenced by British colonialism. Most local people can speak English, and now education also advocates learning foreign languages. So when you go to Hongkong, anyone with a certain cultural background can speak English, unlike Chinese mainland. This is basically a habit of Hong Kong people, and it is not surprising to see it on TV. Moreover, Hong Kong can be said to be a world-class metropolis, with many foreign businessmen and foreigners and many foreign goods, so some foreign product names are not called directly in Chinese, just like iPhone. Don't most people in Chinese mainland also shout English?
