Calligraphy and Tai Chi are both rigid and flexible. Both pay attention to breathing, inner peace and the unity of body, mind and nature. Both of them are healthy, which is a way to cultivate one's morality.
Calligraphy can nourish qi and help qi. Tai Ji Chuan attaches great importance to practicing Qi, and attaches great importance to the use of "strength" in the process of practicing. Everyone pays attention to both rigidity and softness, and pays great attention to emotions, which requires the yogi to "meditate". And cultivate patience and perseverance.
When you are learning Tai Chi, you can imagine yourself writing with pen and ink. Imagine writing with a pen is Tai Chi, sometimes leisurely and sometimes hearty. There must be something in common between them. Both Tai Ji Chuan and calligraphy can cultivate temperament and sentiment in the process of practice, while most people who practice boxing can write and write calligraphy.
