Isn't Carina Lau from Suzhou? Why is Carina Lau's Mandarin so poor?

The long-term isolation between Hong Kong and the mainland has made Hong Kong people very exclusive, and it is difficult to survive if they cannot integrate well into the local area. Artists from the mainland who come to Hong Kong are all like this. If you can't speak Cantonese well, you will be discriminated against, which was not the case in Faye Wong at that time. When Carina Lau arrived in Hong Kong from Suzhou, she began to learn Cantonese because Suzhou dialect was rejected by wireless.
