Are there any language barriers for mainlanders to travel to Hong Kong?

No, there are many mainlanders going to Hongkong from China now. They say Hong Kong people are smart, too. They are required to learn Mandarin at school because Hong Kong returned to the motherland in 1997. Besides, there is a charge for playing. Now who wants to make money from each other without letting them understand, how can he make money?
