1997, before Hong Kong's return to China, which countries did those Hong Kong tycoons emigrate to?

As a result, the living conditions in Canada and Australia are quite poor, and they are not as good as Hong Kong after the reunification. Our teacher said that the places they went to were already unsuitable or poorly developed places in these countries, equivalent to the western part of China, but the immigrants didn't know that the governments of these countries actually let these wealthy businessmen go by deception, and they also paid a lot of money, almost 60%. These people think they can earn back their past. In fact, there are no business opportunities in these places at all. When they went, the living environment and living conditions were very poor, not comparable to Hong Kong. As a result, they couldn't come back when they wanted to, and foreigners cheated them out of all their money.
