What does it mean that the moon shines on the mountains and rivers?

This poem means that a bright moon shines on the mountains and rivers of the motherland.

This poem comes from "Thinking about 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 beautiful night scene or the feeling of missing distant relatives. For example, Publicity Department of the Communist Party of China once awarded the title of "model of the times" to Zhang Yugen, a people's teacher, and published advanced deeds, among which the poem "A bright moon shines on mountains and rivers" was mentioned to describe the spirit of Mr. Zhang 17 who took root in the mountains and devoted himself to the front line of rural education.
