Every coin has two sides. The advantage is that you can adapt to life abroad in advance and lay the foundation for applying for a good university in North America in the future. The disadvantage is that children have no self-control in living abroad, and life in North America is relatively free. If they don't develop good study habits, they may not be able to go to a good university in the future, or they may not be able to adapt to domestic life. Let's just say that the child went to Canada, just like a child who grew up in Canada. Some children in Canada study well, some fail, some succeed and some fail. These are all the same, and it will be difficult to control in the future. Besides, he may encounter more difficulties than ordinary Canadian children, because he grew up far away from his relatives. If you finish high school or university in China and then study abroad, you will have a stronger purpose and self-control, but you may not be able to integrate into local life. It depends on your purpose of studying abroad and your specific ideas.
