After Yu Shuguang graduated from high school in 1962, he worked as a worker, artist and performer. He cultivated and accumulated various literary and artistic talents in practical work, and also developed a simple and pragmatic character. .
In 1985, he entered the Chinese Calligraphers Association, the highest organization in the calligraphy world. Later he served as editor, office director, and research director. If he wants to take a shortcut and stay close to the water tower, it should be easier. However, he believes that although seeking quick results, taking shortcuts, and following the trend can achieve some benefits, it will never become a big success. It is a kind of "new book slave" and loses self. Therefore, he calls himself a "study of bitterness".
He attaches great importance to tradition and bases himself on studying traditional classics. He is almost omnipresent in the excellent ancient inscriptions, "for my own use" and thinks that he "does not let the ancients". He had a special liking for the four families of the Song Dynasty and Wang Xizhi. He has made great achievements in studying "Lanting", and his "The Best Running Script in the World" compiled by him has considerable influence in the calligraphy circle. He put great effort into ancient classic calligraphy, and his calligraphy should be meticulous and meticulous, pursuing both form and spirit. He strived to combine the calligraphy with his personal hobbies and take the road of innovation. We should always pursue the beauty of strength, the beauty of pointillism, and the beauty of overall effect and breath rhythm. In calligraphy creation, he is good at all styles, but his focus is running script and cursive script. The strokes of his seal script are smooth and not rigid, and his regular script is mostly based on scriptures and bamboo slips, and also absorbs the calligraphy techniques of Su Shi, Ni Zan and others, making it more attractive. His cursive script has absorbed the styles of many masters since the Tang and Song Dynasties, adopting the best methods and pursuing their gods. His cursive writing works are often full of momentum, strong and smooth, and sometimes dry and thirsty, showing signs of old age and vigor. Shu Guang is a calligrapher and painter, so his calligraphy works often feature rich variations in ink color. This is also a rare artistic effect.
