A trip to Hong Kong

In Hong Kong, people speak Cantonese, mandarin and English.
Local people usually speak Cantonese.
Cantonese has a strong accent like quarrels.
I think that it is one of the reasons which give Hong Kong activity.
English speaking ability would give more chances to get a better job in Hong Kong.
Hong Kong is a big Asian financial center.
There are many financial companies from all over the world, and many European and American business persons working in Hong Kong.
