(The art of calligraphy is the crystallization of the wisdom of Chinese civilization and the lifeblood of Chinese cultural heritage. As the saying goes, "words are like a person", words are like a person's second appearance, reflecting a person's cultivation, character, knowledge and even health. Regularly writing the classics of ancient sages and sages is not only beneficial to the harmony of body and mind, but also cultivates concentration, nourishes the mind and calms the mind. Under the influence of moistening things with silent calligraphy, the heart will naturally shine and be happy.)
