I think that when it comes to children's painting, we should not consider the age at which they should start, but should consider whether the child has become interested in painting. Being interested has nothing to do with age.
If you start painting at the age of 5 as everyone else says, you will often not be able to develop high painting abilities and achieve good results. When interest arises, children are more willing to get involved and make faster progress.
Tell me two real examples. Let me first talk about my little nephew, who is 8 years old this year. He started to learn painting formally when he was 6 years old. Before the age of 6, he could draw things to express his thoughts. He also likes colors. His mother bought him the three elements of red, yellow and blue. She told him about the color matching, and he was able to mix the colors himself and draw what he imagined. With such strong interest, I started to learn painting. After two years of professional study, I can see that he has made great progress. A watercolor painting of "Snowy Night" he painted is hanging on the wall of my house. Every friend who comes to my house says it is very good.
Let’s talk about the story of Grandma Moses. She was one of America's primitivist painters. She was a farm worker and loved embroidery. I had to give up embroidery because of arthritis and started painting at the age of 76. When he was 80 years old, his solo exhibition in New York caused a sensation. In his painting career of more than 20 years, he created 1,600 works.
Qi Baishi, the master of modern Chinese painting, was a carpenter in his early days. He began to learn portrait painting under his apprenticeship when he was 24 years old. After decades of accumulation, he became a master.
Some people show interest in painting at a young age, while others only discover that they like painting after they become adults. No matter how old you are, you can draw as long as you feel like it. Interest is the catalyst that keeps us moving forward.
