Calligraphy and martial arts have the same effect in different fields. Calligraphy pays attention to the use of penetration, Yin Yinni and leakage marks. It is as soft as a feather, as heavy as a falling stone, as fast as a snake and as slow as a cone painting stone. So writing with a pen refers to exertion, wrist force and elbow force. Do it with your whole heart, so there is a saying that you should write first, which is also the highest realm of calligraphy.
Wushu swordsmanship is practiced steadily, accurately and accurately, and the strength is used to achieve the unity of man and sword with sword. Its use of force can be said to be completely consistent with calligraphy. Calligraphy can also achieve the unity of human and pen, and its similarity lies in the handheld device, which is intended to run through the arm. Pure personal opinion, please forgive me for my shortcomings.
