Li Yangbing is a disciple of Xiao Yingshi, an advocate of ancient Chinese prose movement. In his early years, he studied Ci as a subject, and his articles were concise and elegant, which allowed him to be a "great master of a generation." He was appointed as a county commandant of Shangyuan County, and in the second year of Ganyuan (759), he was appointed as Jinyunling. In August of that year, there was a drought in Jinyun County, and Li Yangbing led the people to pray for rain in the Chenghuang Temple. "The ice bow prayed to God, and God said,' If it doesn't rain for five days, it will burn its temple.' When the time comes, the heavy rain will come to an end, and the officials and officials will \. In the second year of Shangyuan (761), Li Yangbing moved to Dangtu again. In the autumn and winter of Baoying's first year (762), Li Bai exiled Yelang to meet forgiveness, returned to Xunyang, and came to Li Yangbing, the uncle of Yi nationality. He died in November, and entrusted the manuscript to Li Yangbing on his deathbed. Please arrange it for him. Since then, there has also been a "stone letter from the tyrant who cultivated the land at the beginning of the Dali period", among which there are 23 chapters of the "Filial Piety" written by the silk element ancient liberal arts. Li Bai was first introduced, and Li Bai granted Bing Yang all his laws. " However, at the beginning of the Dali period (766-768), Li Bai had been driving a crane to the west for five years, which should be interpreted as a legend by future generations. In the second year of Baoying (763), Li Yangbing retired to the mountains of Jinyun, where he spent more than ten years, during which he made great progress in calligraphy. In about seven or eight years of Dali (722 and 773), Li Yangbing arrived at the mountain and served as the Facao of Jingzhao House. In the 12th year of Dali (777), Li Han, a Suzhou secretariat and imperial historian, visited Li Yangbing, asked for a simplified inscription, and then wrote "On Ancient Seal Calligraphy by Dr. Li Shang", expounding his understanding of seal calligraphy, and issued a grand wish to seal six classics and establish "The Classic of the Tang Dynasty". In the first year of Jianzhong (78), Li Yangbing had many friends with Yan Zhenqing, including Yan's tablet and Li Yangbing's seal. Around the first year of Xingyuan (784), Li Yangbing was appointed as a less supervisor, then as a secretary and finally took office; Therefore, the world also calls it "Li Shaojian" and "Li Jian".
Li Yangbing's title was very popular in the Tang Dynasty. At that time, people praised him as "a tiger with a pen" and "a pale back", and called him "after Li Si, only one person." However, there is no biography of the old and new Tang Shu, and his life story was first found in the Shu Shu Fu written by Dou Yu and Dou Meng in Tang Dynasty and the note:
"Zhao Jun Li Jun is a well-connected family. "Yishan" is parallel, proclaiming that the father is in the same group. The hole is in the study of characters, and the ancient and modern texts. Filial piety is passed down from family to family. Note: Li Yangbing, a native of Zhao County, was born to Yong Men, the father of Hu Cheng Ling. The five Bing brothers, who were dedicated to Ci studies and devoted themselves to Xiao Zhuan, first studied Li Si's Yi Mountain Monument, and later saw Zhong Ni's Wu Jili's Epitaph, and then changed on and off, like a tiger, vigorous and generous, and became popular in rain collection. The essence of words is known in the mind, and those who know it are called pale and backward. Brother slack, slack son Teng, ice son are all, and the word field is high. The youngest son is broad-minded, diligent in learning filial piety, and is the same as his children because of his family. "
Since then, there have been many discussions about Li Yangbing's life story, but the details are not clear. The important materials we can see now are Song Zhu Changwen's Continued Book Break and Xuanhe Book Score. A more detailed study should be made of Li Yangbing and the famous seal writers in Zhu Guantian's "A Brief Examination of Li Yangbing" and "The History of Calligraphy in China, Sui, Tang and Five Dynasties".
Wu Qiuyan, a Yuan Dynasty man, once put forward the view that Li Yangbing is Li Chao. In Xuegu Bian, he said: "Yang Bing is famous for his tide, and Du Fu's nephew is also a nephew. Later, he used the word line, because he thought it was a name, but other words were less warm. There is a cloud in Mu Xuanxu's "Hai Fu":' Under it, Bing Yang is not cured, and the yin fire is latent, so it is reasonable to know and tide.' " Liu Xizai, a Qing Dynasty man, also supported this theory in his "An Outline of Art", and put forward support opinions from the names and characters of Li Yangbing brothers and the handed down works of Li Yangbing and Li Chao. Although their views are recognized by some people, most people don't agree with this formulation, and Gu Yanwu of Qing Dynasty refuted this in detail: "Zhao Jun, a native of Bing Yang, is an uncle of Taibai nationality, and his words are less warm, which is found in Xuanhe Shupu, corresponding to his name. If it's a tide, it's meaningless to take Bing Yang and Shaowen as words. Yang Binggong's seal-writing is eight points, and Zhao's Records of the Stone Inscription, Memories of the Temple of God in the City God, Memories of the Temple of Confucius, Monuments to the Ancestors and Records of the Three Graves are Li Yangbing's seal-writing, while the Monument to Maitreya in Huiyi Temple and the Epitaph of Peng Yuanyao are Li Chaoshu's. For this reason, Mr. Zhu Guantian made a detailed discussion on Li Yangbing and Li Chao, re-establishing the fact that Li Yangbing and Li Chao are not the same person.
