English major's answer, learn English pronunciation or American pronunciation?

Generally speaking, British pronunciation is a universal standard, and American pronunciation can only be regarded as one of dialects, just like the difference between Mandarin and hometown dialect. Of course, children have the priority to learn to speak Mandarin. Of course, things are not absolute. Even in Britain, English has different accents due to regional differences, not to mention in the United States. Therefore, it is generally inaccurate to distinguish English pronunciation from American pronunciation. You can learn an English accent that suits you and can be understood by foreigners. It is more suitable for listening to the pronunciation of CCTV9 channel announcer. After all, your oral muscles haven't grown to the state of foreigners, except those from China who have lived in Britain and America since childhood. Wish you success!
