How to persuade family members not to go to school?

Three years ago, when I told my parents that three of us were going to immigrate to Australia, my mother's tears fell down and I couldn't help it. After that, for about half a year, we didn't speak on this issue. We learn to let our parents accept it from another angle, instead of just opening our mouths and saying it. Let them know about Australia's welfare, children's education, work wages, etc ... slowly, they can talk to us about this issue, and then we have a second baby, that is to say, we are facing an immigrant of a family of four. My mother-in-law has a classic saying, "We just spent money to buy a five-guarantee household." We have completed all relevant procedures since last year. This process requires patience. You are the only child whose parents won't let you go. You have to understand. You should let them know that you go out to study better, improve yourself and live a better life. You can choose to return to China after studying abroad, of course. Parents want a better life for their children. Looking at you every day, life is not satisfactory, what is the point? If one day my daughter tells me that they are going to America, even if I have 10 thousand, as long as she tells me, she will get a better life and be very happy. I will not hesitate to agree and support. If I was still financially capable, I would consider living with them.
