About Canadian immigration, how to pay the landing fee of HK$6,250 per person

You can contact the Canadian embassy or consulate in Beijing and Hong Kong, China, and they will give you an Immigration Bureau account. Just pay the money through a Chinese bank. However, there is no need to apply for expediting.

Or, you can go to a Canadian bank in China and buy a check. I will give it to you when you enter the customs, but it is troublesome and you cannot enter the customs immediately.
