Hello, the boy's job you mentioned is a way to lay the foundation for the practice of a certain industry from an early age. Since it is one of the ways, it cannot be directly equated with the industry. I guess what you want to express is whether painting can only be successful from primary school, then I can tell you for sure, no. Many people learn painting from childhood, but the subsequent development path is uncertain, and they may give up halfway. If you mean that people who learn from primary school are better than those who learn the day after tomorrow (of the same age), that's not necessarily true, because painting emphasizes not only skills and experience, but also inspiration, spirituality, understanding and talent, all of which are based on the mind. So, what I want to say is that as long as you find your own talent, you will certainly achieve something even as an adult. Listening can die at dusk, and so can old people.
I know a famous painter in Yibin who spent his first twenty years tossing and turning. It was not until he was twenty-five that he began to learn calligraphy and Chinese painting. Now that he is almost seventy, grapes are a must. There are still many people who study painting unconditionally for several hours, not only drawing socially recognized paintings, but also writing biographies and compiling painting collections. Furthermore, isn't Walter Disney, the father of Mickey Mouse, the same?
