Throughout Li's life, he became an official because of his father, but he was not allowed to display his ambition because of his father. He only serves as his father's assistant and will always be an angry and tragic figure. He never caught up with his father's many years of military exploits in his life, nor did he get a good job in cotton mills, power plants, telegraph offices and other units in the rising Westernization Movement. Instead, I have been following my father and doing the most thankless business of "weak countries without diplomacy", so I can't shine in politics all my life, but I can only be unhappy. Although he is extremely smart and capable, proficient in five languages and scripts, good at writing official script and cursive script, and although he is not tall and handsome, he is always strictly bound by his father and has no chance to display his ambitions all his life.

Li experienced so many important things in the diplomatic affairs of the Qing Dynasty-treaty of shimonoseki, the secret agreement between China and Russia, and the trip to Europe with his father ... There must be a diary or personal file, but it's a pity that I can't find it now. According to Li's grandson, Li, the rebels stole many things from his home during the Cultural Revolution, including Wen Zhonggong's letter, which was a large personal letter from Li Hongzhang to Li. In addition to taking care of him to deal with some big family matters, such as property disputes at home after Li Fengzhang's death, the concubines complained bitterly about Li Hongzhang. No one else wanted to intervene, so Li Hongzhang had to ask Li to go to Anhui to deal with this matter. There is also the matter of Yicun Yitian in the countryside. Li Hongzhang also takes care of his eldest son, Cha. More letters are to inform the situation, including the personnel dynamics in all aspects of the Qing court, to deal with the problems of diplomatic envoys or foreign firms, and to analyze the situation. Politics, economy and diplomacy are all intimate, and there is no taboo, which just shows Li's position in his father's mind.

However, when the policy was implemented and the property materials were returned after the Cultural Revolution, the official did not return all these manuscripts to the Li family. At present, the place with the largest collection of Li's handwriting is probably the Shanghai Archives, which contains more than 0/00 letters of Li.

Li advocates the abolition of foot binding. Although not very successful, he persuaded his father, Li Hongzhang. With Li Hongzhang's acquiescence, Li Jiacheng let go of the bureaucratic family for a few women.
