This poem comes from the poem Thinking of a Quiet Night by Li Bai, a poet in the Tang Dynasty. This poem describes Li Bai's feelings of missing his hometown and relatives at night, and expresses his loneliness and homesickness by depicting natural scenery. This poem has become a classic in China's ancient poetry and has been widely read and appreciated.
In modern times, the phrase "a bright moon shines on mountains and rivers" is often quoted and imitated to describe the feelings of beautiful night scenes or missing distant relatives. For example, the Central Propaganda Department once awarded the title of "model of the times" to Zhang Yugun, a people's teacher, and published advanced deeds, in which the poem "A bright moon shines on mountains and rivers" was mentioned, which was used to describe the spirit of Mr. Zhang who had been rooted in the mountains for 17 years and devoted himself to rural education.
