If you spend 1000 yuan a month and you can get10/0/yuan of passive income without any effort, then you have achieved this enviable financial freedom. The thousand yuan in this example is called the "critical point".
Once financial freedom breaks through this critical point, as long as there is no catastrophe, you can live without working. Of course, if you like your job, you can continue to do it, or you can choose what you really like to do, instead of doing things that you are unwilling but helpless because of life.
A set of property that is rented out for profit is an asset, because it is completely owned by you, and the monthly income offsets the property tax you pay and there is a surplus. The house you live in is no longer an asset, because you have to bear the mortgage and the resulting loan interest. Even if you pay off the mortgage and loan interest, you have to bear the expenses of housing maintenance, property tax and other projects.
