Let's take a look at Huang Tingjian, a famous writer and calligrapher in the Northern Song Dynasty. Calligraphy has its own characteristics, which is one of the characteristics of Song Sijia. Many famous works, one is Song Fengge's poem post and the other is a banquet post. His poems are very famous. He is also a pioneer of Jiangxi Poetry School. His poems are very powerful. And his handwriting is also very powerful. Very good at running script, cursive script and regular script. He strongly recommended Wang Xizhi's Preface to the Lanting Pavilion. This Huang Tingjian was also influenced by Su Shi. At that time, Huang Tingjian dated back to the Jin and Tang Dynasties. Su Shi had a great influence on his ancestors' calligraphy at that time. At that time, many of Huang Tingjian's hand-tied scripts were based on Su Shi. In my opinion, the calligraphy attainments of these two people are very profound and inseparable. First of all, they are not calligraphers of the same period, one is the Tang Dynasty, the other is the Northern Song Dynasty, and their styles are different. Even contemporary calligraphers can't give a clear answer. Besides, the two are not in the same period. But from the point of view of fame alone, Huang Tingjian is better, but this is not a good criterion. Both of them are very good at calligraphy, each with his own strong points.
