What kind is it? The author has consulted the materials and tends to the first statement.
Li Hesheng was born in 790 AD. At the age of 20, he went to Chang 'an to take the imperial examination. After his failure, he returned to his hometown of Changgu. Later, in order to make a living, I lived in Chang 'an for a long time. It was not until 809 that I won Feng's small official position from Jiupin because of my kindness. What does Bon Li Lang do? In the Tang Dynasty, there were four people, who belonged to Taichang Temple according to the nine categories and held the position of monarch and minister to sacrifice to the court. Popular point is the emcee who presides over the sacrificial ceremony. Li He served as Li Lang for three years. He didn't lead troops to fight, nor did he go to the buffer region of Hebei. It is likely that he heard that the emperor sent Zhang Xu to crusade against the Yanmenguan rebellion and improvised poems to boost morale.
It is said that he is in Chang 'an. Although he can't take part in the battle directly, he has the opportunity to hear the news of the battle. It is not difficult to write the battle scenes with his rich imagination. Moreover, Li He is not satisfied with Feng's position. What he wants to do most is to go to the border to fight and serve his country. This is similar to the ideal of many poets in the Tang Dynasty who abandoned their pens to join the army. For example, Wang Bo, one of the four outstanding figures in the early Tang Dynasty, revealed his idea of joining the army in Preface to Wang Tengting. Cen Can, Gao Shi and Wang Changling are all frontier poets. His greatest wish is to lead the troops to fight on the battlefield and die in battle. He wrote in "Thirteen Poems of South Garden (Part II)", "Why don't people take Wu Gou and gather fifty states in Guanshan?"? How brave and ambitious! It's a pity that he failed the imperial examination and had no good chance to join the army. He can only write some poems expressing his ideals and ambitions by imagination. Yanmen Taishouxing painted the tragic picture of the war with imagination and expressed his determination to serve the country with allusions.
We always say that we always want what we don't have. For Li He, his defect is his ideal. He is thin and has a strange appearance. But this does not affect his lofty aspirations, nor can it erase his desire to go to the border to fight. However, he worked as a servant for three years and wrote dozens of poems expressing his love for the country, but he failed to realize his lifelong wish and had to die of depression.
The second statement is not appropriate. First, Zhang Gu's leisure proposition is an anecdote of the Tang Dynasty and an official unofficial history, and there is no reliable basis. Second, in 807, Li Henian was only 18 years old and had not yet gone to Chang 'an. Even if I had the opportunity to write poems for Han Yu, I didn't have the opportunity to know about the separatist regime in Hebei. Third, he is still very confident in the imperial examination at this time. If he can pass the exam, he will have a better chance to serve the country. After all, the ideal of ancient scholars was to study for officials. Li He has read many poems since he was a child. He is a descendant of Tang Gaozu's uncle Zheng Wang. Being an official is the right way. Besides, he was once in poor health, how could he go to the border to fight? The ideal of going to the border to fight is an ideal of helplessness after the imperial examination is hopeless.
In a word, Li He's poems with various themes can reflect his dissatisfaction with reality, thus producing surreal ideals and satisfying his unfulfilled wishes through imagination.
