What thoughts and feelings does Wang Jian's poem "Looking at the Moon on the 15th" express?

Expressed the author's homesickness.

Wang Jian's fifteenth full moon

Bai Shu roosts in the atrium, and Coody Leng is silent and wet with osmanthus;

The moon is full of hope tonight. I don't know whose house Qiu Si will be in.

Wang Jian was a poet in the early Tang Dynasty and a native of Xuchang, Henan Province. The poet was poor all his life and "joined the army for thirteen years", but he lived in his hometown "all day long." After forty years old, he became a white-haired official, and then he fell to the next position, where he became a county magistrate and Sima, known as Wang Sima. Therefore, the poet has the opportunity to get in touch with the lower classes and understand their sufferings.

Looking at the moon on the fifteenth day is a poem with melancholy thoughts. "Crows inhabit Bai Shu atrium, and Coody Leng osmanthus is silent." The fifteenth day of the lunar calendar is a full moon, and the courtyard illuminated by moonlight is very bright. The author vividly depicts a picture of a courtyard: bright moon, courtyard, trees, crows, Coody Leng and osmanthus. Because the moonlight is bright and the ground is white, the author can vaguely see that crows are still living in trees. Coody Leng shows the cold in autumn, while Coody Leng silently sets off a quiet word, which adds to the poet's melancholy. Li Bai once wrote, "The autumn wind is clear, the autumn moon is bright, the fallen leaves gather and disperse, and the western Western jackdaw is surprised." . Acacia knows when to meet, and this night is embarrassing. "Show a moving Qiu Si. The autumn wind blows, and the fallen leaves gather and disperse, which brings an alarm to Western jackdaw in the west, thus showing a flowing picture. Wang Jian's Fifteenth Full Moon shows a quiet and lonely melancholy more emphatically.

"I don't know who will fall in Qiu Si tonight." The poet turned to describe people, and people who are homesick and miss their loved ones look up at the fifteenth moon, trying to convey their deep feelings of missing to people or things through the moon. The poet expressed people's strong yearning through a word "exhaustion". I don't know whose house Qiu Si will stay at. An "Autumn" shows people's heavy worries, deep thoughts and homesickness. In ancient times, without modern communication tools, a letter from home would take several months to arrive, so we had to borrow the bright moon to send homesickness. Du Fu once wrote a poem "Remembering my brother on a moonlit night", "Wanderers listen to drums and geese sing autumn colors. He knows that the dew will be frost tonight, and how bright the moonlight is at home! Compared with Wang Jian's "Looking at the Moon in the Fifteenth Year", there are many similarities. "He knows that the dew will be frost tonight, and how bright the moonlight is at home!" It has shown strong thoughts and feelings, so it has been passed down through the ages and is more well known.
