During the Jin and Tang dynasties, some calligraphers were both civil and military, so they were able to have a strong body and write strong words. Later generations all think that the calligraphy in Jin and Tang Dynasties is vigorous and magnificent, which is somewhat different from the beauty of calligraphy in Song Dynasty. People who practice martial arts often have to hold swords, which requires strong wrists, similar to writing brush strokes. Just like Li Bai, he learned simplified Chinese characters himself, so the words he wrote are also very imposing.
As a well-known calligrapher, Wang Xizhi's teacher, Mrs. Wei, was born in a military family at that time, so Wang Xizhi's calligraphy also has a military flavor. And Yan Zhenqing, a great calligrapher in the Tang Dynasty, created a font that is now praised by people? Face? He is a plain satrap, and he participated in the war during the An Shi Rebellion, so his calligraphy is also very imposing, and you can feel his martial arts at a glance.
Because after the Song Dynasty, the separation of civil servants and military attaché s made many calligraphers' handwriting more delicate than that of Jin and Tang Dynasties, and there was no strong feeling. So this is why those calligraphers in the Jin and Tang Dynasties have made such great achievements and written calligraphy with such style. In fact, this has certain reference significance for our later generations.
