Personally suggest calligraphy. I have studied calligraphy for 7 years, and I can write in all kinds of calligraphy styles. Hard-pen calligraphy is also very beautiful now, and learning calligraphy will definitely drive hard-pen calligraphy. Speech is a representation. Not only that, you need to keep calm in the process of learning to write, which is very good for individuals. However, learning calligraphy will be boring for a while, but almost all children will be like this. You must let the child stick to it and get through that fatigue period.
Painting is ok, but if you don't plan to major in the future, you will rarely use it. But it is also good for girls to learn to draw.
