What is the name of the handwriting written by the calligraphy teacher?

Since ancient times, people have regarded the words written by calligraphers as "Mo Bao". Calligraphy contains all the artistic writing of Chinese characters in China. Therefore, Chinese characters with different fonts have their nicknames. Calligraphy is a unique and flexible writing tool in China, which is formed by artistic conception and mobilizing artistic techniques according to the characteristics of Chinese character modeling. So "calligraphy" itself has no other name.
