If you really want to learn calligraphy, or write, it is most important to write first. Don't worry about your age. No matter what the reason, the missed age (time) can't be recovered. Only by grasping the present and starting at once is it.
Of course, learning calligraphy and practicing calligraphy are the same as other skills. If conditions permit, it is certainly good to practice "childlike innocence" from an early age. For example, Sun Xiaoyun, the chairman of China Calligraphy Association, was forced to practice calligraphy at the age of three, and made great achievements in calligraphy.
Mr. Lin Sanzhi, a "contemporary sage of grass", began to love cursive script at the age of 60 and worked tirelessly for more than 20 years, eventually becoming a master.
Times are different. Today's children basically have the conditions for calligraphy or writing from primary school. Our parents should cherish and make good use of the prime time of practicing calligraphy in primary schools.
There used to be a popular saying: you can't lose at the starting line!
In view of the current educational system arrangement and the relevant regulations that kindergartens cannot be primary schools, six years old should be regarded as the real starting line of life, and the most suitable age for calligraphy writing enlightenment should also be six years old.
