It shows that the imperial examination in Tang Dynasty clearly distinguishes between classics and scholars. The Ming Classics mainly test four books and five classics, which is similar to filling in the blanks. For example, when the test paper asks "Confucius, when will Xi be", candidates only need to fill in "learning", mainly for endorsement; The strategy of Jinshi's examination of poetry and fu is basically equivalent to the current composition and current affairs politics, which is more difficult. At that time, there was a saying called "Ming Jing at the age of 30, Jinshi at the age of 50", which meant that after being admitted, it was too late to take the exam at the age of 30, and Jinshi was not easy to take the exam. At the age of 50, he is also a young man. At that time, if you talked to people about poetry, you would be despised. Of course, it is also related to Li He's personality. What Li He means here is that once he passed the Ming Jing, he became famous by endorsement, but he didn't write poetry. You and I don't have the same language. Something like that, so I offended Yuan Zhen.
Regarding taboos, I remember that Li He's father's name is Li Jinsu, and there is a gold word in his name. At that time, some people said that if Li He was admitted to Jinshi, others would have to call him Li Jinshi, which violated his father's taboo. For filial piety, he should not be a scholar. Han Yu's article is also very famous, which mentions that "the father's name is Jin Su, and the son is not a scholar; Father's name is benevolence, but son can't be human? " In other words, if you say a father's name is Jin Su's son, he can't be a scholar. If the father's surname is Ren, can't the son be a man? But in the end, Li He didn't win the first prize for life. The translation here follows your quotation for reference only.
