Did the teacher immigrate to Canada or Australia at the age of 30?

It depends on what kind of life you aspire to. To tell the truth, Canada and Australia are really different. Mainly depends on which city you are compared with which city. . . But personally, I think Australia is still relatively expensive. In fact, the living standards of non-small cities in Canada are not much different from those of first-tier cities in China. If we compare Sydney, ordinary consumption can lead to excessive consumption in China. I suggest studying first and listening to my friends' advice, but Canadian medical insurance is really rubbish. Australia has done better in this regard.
