Discovered this idea when you first took the traditional painting class -- you first took calligraphy, then did art -- in calligraphy, you had to stricly follow what the original author did, just like you are copying other's work -- so it's not so interesting -- but in the art class, the teacher may set a topic for you, but you can express it in your own way -- in the first class, you were told to paint a monkey, but everyone ended up with very different monkeys, with different spirits, facial expressions, gestures -- this really reflects what kind of people the artists are. For example, your teacher says she is very sensitive about all the strokes she paints, so she is probably a sensitive person emotionally
