Emperor Xuanzong of the Tang Dynasty was one of the most controversial emperors in the history of China. He created the "Kaiyuan Shengshi" with his own hands, which was the highest peak of the Tang Dynasty and even the whole feudal society, but he personally ruined this great era and pushed it to the abyss of "An Shi Rebellion". There are many reasons why he changed from a wise king to a faint king, and improper employment is a very important one. He appointed many prime ministers, including Yao Chong and Song Jing in the early stage, Zhang Jiuling in the middle stage, and only Li and Yang in the later stage. When Zhang Jiuling left, people at that time wouldn't realize that he was the surname of the prosperous Tang Dynasty and took away the last breeze of the imperial court. Zhang Jiuling can't beat the traitor Lee. Go to Jingzhou for a long time after being demoted. Such an upright and wise elder can no longer protect moderns in the Tang Dynasty, but can only fly away. After a long journey, he wrote many poems in Jingzhou, most of which are sentimental works, including twelve kinds of feelings, and this famous looking at the moon and thinking of one far away: Moon, which is now complete at sea and illuminates the whole heaven. People who love hate long nights and sleepless nights and miss their loved ones. Put out the candle to love this moonlit room, and I wander in the deep night dew in my clothes. You can't have beautiful moonlight, just want to meet you in your dreams. This poem is very popular, and it is also a must in the anthology of poems and songs in the Tang Dynasty. In Xiao Jue's view, it is not only lofty in artistic conception, but also a blend of scenes and scenes, reaching a high artistic realm, and it is also the last elegant demeanor of the prosperous Tang Dynasty. Marked by this, the Tang Dynasty gradually declined until it was out of control. The first sentence in this famous article is an unforgettable swan song. The word "the moon, now full of the sea, illuminates the whole heaven" doesn't seem surprising or exaggerated, but when these ten ordinary Chinese characters are connected together, an incredible chemical reaction will occur. It is full of verve and exquisite workmanship, which perfectly links the wonderful beauty of nature with the poet's yearning for distant relatives. Throughout the ages, many scholars like this poem. Behind the lovesickness, it is not weeping or lamenting, but the unique enthusiasm of Datang. The third and fourth sentences are about people, and later people interpret them as the author himself, while others interpret them as lovers. In my opinion, it makes no difference. On this bright night, of course, there are lovers, including the author. Because they can't get together, they resent staying up all night, which reminds them of the pain of missing. The fifth and sixth sentences are closely related to the above contents. The people in the poem may be preoccupied. People who can't sleep well get up and blow out the candles and go outside to enjoy the bright moon. Seeing the bright moon is more difficult to sleep. Late at night, dew splashed all over his clothes. These two sentences not only describe the scene of sleepless nights on the moon, but also add vitality to the whole poem, which is no longer a static picture. In the last two sentences, the poet actually used the phrase "although there is a glow, it is not enough to win it." This is a famous sentence of Lu Ji in the Jin Dynasty, which was rewritten by Zhang Jiuling and is more poetic. He wrote about a wandering man who had nothing to give to his distant relatives. He can only hold this beautiful silver light and dream of seeing them as soon as possible. The poem came to an abrupt end, leaving readers with lingering aftertaste. This song "Looking at the Moon, Thinking of One Distance" has also become a masterpiece of missing loved ones for thousands of years, and has been praised by future generations. Its first sentence has become one of the most mentioned poems during the Mid-Autumn Festival.
