If you want to concentrate on painting, it is necessary to have a certain economic foundation. Because if you don't work for three years, you should be able to live on your own savings of 30 thousand yuan, which is a bit tight, because your painting supplies and so on are very expensive. Although it is said that you can concentrate on painting, it is not recommended to do nothing. You can work for half a day, draw for half a day, and support yourself.
