How is the age of calligraphy divided?

You should not be too young to learn calligraphy. Generally speaking, a person should start writing according to the simple words that children know when he is just in primary school, that is, when he is 6 or 7 years old. Children learn calligraphy in two stages: hard pen learning and soft pen learning. Cai Jiajun, a senior calligraphy teacher, believes that the best time for children to learn hard pen calligraphy is about 6 years old, and the best time for children to learn soft pen calligraphy is about 7 years old.
