First, calligraphy is mainly about self-cultivation. There is a saying in the ancient literati class that one should cultivate one's morality and cultivate one's nature all his life, and govern the country and level the world. Of these four items, self-cultivation is the foundation and the most important. Self-cultivation is a kind of character, a calm state, and a firmness that is not disturbed by evil thoughts, which is included in the process of practicing Chinese characters in ancient China. Therefore, the reason why calligraphy is so emphasized is to achieve the effect of self-cultivation.
Second, calligraphy was popular in the upper class at first, and then it was popular all over the country. The concept of calligraphy began in the Eastern Jin Dynasty, because at that time our regular script really became popular. The most famous is Wang Xizhi, who was later praised as a book saint. Later, it was something that only princes and nobles were qualified to learn. However, the establishment of the imperial examination system after the Sui Dynasty provided a foundation for children from poor families to enter the historical stage, and calligraphy also entered thousands of households at this time.
Third, culture itself has no monopoly. You know, if a civilization becomes a cultural phenomenon, then it exists for communication, so there is no monopoly. The concept of monopoly is mainly to obtain certain benefits, while culture does not obtain benefits, but brings benefits to people. Therefore, it is not a cultural monopoly that the ancient people asked to practice calligraphy, but the result of the wide spread of culture. Finally, whether ancient or modern, practicing calligraphy is a multi-purpose thing, and there is no need to be associated with the word monopoly.
