The meaning of the above two poems is: the dew is particularly light tonight, and the hometown month is particularly bright. Why is this happening? Because the poet Du Fu experienced the great turmoil of An Shi Rebellion, he had to give up his official position in the autumn of 759 BC and live in Qin Zhou (now Tianshui, Gansu) under the condition that his country's future and personal destiny were constantly hit. In this desolate and desert border town, the poet moved his homesickness to the dew and moonlight, which set off his homesickness with the infected dew and moonlight, blending things with people, thus better expressing his strong homesickness.
They all use empathy rhetoric to move people's feelings to things. In this way, human feelings and things will be integrated into one, which can better express people's strong feelings.
