There are inherent constraints among "frontier fortress", "bright moon" and "Guan", which form an inseparable organism, so the creation of frontier fortress poems is often inseparable from the shaping of "bright moon" and "Guan"
As a language image, the moon embellishes the environment into a vast and tragic frontier fortress style, and also transforms the frontier fortress, a unique geographical and physical space, into an artistic psychological space.

The moon rises and sets, and the moon is full and short. Moonlight is passing away, and the passing of moonlight unfolds in the time of life, so moonlight is still life and time. The ancients often used the image of the moon to lament the passage of life and years.
3. The melancholy image of the moon.
In ancient poetry, the moon is still emotional. In nature, the moon is full moon and cloudy day, and full moon and lack of moon are heterogeneous and isomorphic with perfection and lack of moon. Therefore, the moon described by poets is often associated with emotions of emotions.
As a melancholy image, the moon is cleverly conceived. Rich in imagination, ethereal brushwork, lyrical and indirect, full of interest, it has gained immortal artistic life and vague artistic atmosphere.

The moon's broad intentions:
(1) Homesickness or Acacia: The image of the moon reflects the ancient literati's psychology of searching for their mother's world, spiritual home and restoring world harmony and unity. The theme of looking at the moon embodied in classical poems relives the homesickness of old dreams. The moon is a clear and motionless homesickness in the sky. Poets miss their homeland and their parents' affection, and often place their hopes on the transmission of the bright moon. The moon tied the heart of lovesickness and shortened the distance between time and space, which led to the themes of lovesickness and homesickness in Gu Dan and January.
(2) The moon reflects the loneliness and loneliness of ancient poets and the psychology of frustrated people seeking comfort and relief.
(3) The moon's eternal cyclical changes remind people of the dialectical development between the positive and negative sides of time and things in the universe. As a symbolic form, the moon evokes people's boundless cosmic consciousness and historical consciousness, evokes people's lament with a vast space, and touches the distant and desolate original cultural image. Therefore, the appearance of the moon image is always accompanied by the vast and desolate space and the majestic and lofty aesthetic realm of the tragic consciousness of heaven.
(4) As a symbol of eternity and nature, the moon has become the embodiment of scholar-officials who escape from all kinds of real sufferings, stand out from others, and laugh at the mountains and forests. After denying the realistic utilitarian purpose and morality of life, the moon became a personable person.
