Explanation:

Calligraphy is the art of writing beautifully, artistically and correctly formed, following different styles; but it can also be understood as the set of features that characterize the writing of a person or a document.

Chinese culture attaches great importance to calligraphy. This is based on the visual beauty of the ideograms, the technique of their realization and the metaphysical precepts of traditional Chinese culture. Tradition states that Chinese characters, the oldest known form of writing of those existing today, were invented by Cang Jie (around 2650 BC). Another tradition traces its creation to the times of Fuxi, the legendary first emperor of China.
