2. Li He was a famous poet in Tang Dynasty. Due to long-term depression and sentimentality, Yu Yuanhe resigned as the giver due to illness in the eighth year (8 13) and died young at the age of 27. What disease did Li He die of? How Li He died is not clearly recorded, but it can be inferred from Li He's poems and his experience that Li He may have died of depression. Li He's depression and sentimentality are related to his incompetence and frustration in officialdom all his life, and secondly to the early death of his wife. It is precisely because of this life situation and the state of writing poems that Li He's life is not easy and happy. Later, he became depressed and became ill, and the language in his poems was often sad and sentimental.
