In the era of Wang Changling, the development of seven-character quatrains was not mature, and not many people wrote seven-character quatrains. However, Wang Changling has repeatedly created masterpieces, leaving many masterpieces handed down from generation to generation. We now see more than 70 of his seven-character quatrains, accounting for two-fifths of his poems.
In fact, Li Bai is also very good at writing seven-character quatrains, and some well-known masterpieces have been handed down from generation to generation. For example, To Wang Lun is a simple and sincere work. So in history, people often put Wang Changling and Li Bai together.
For example, in the Ming Dynasty, Hu Yinglin once said: "The seven words are absolutely unique, such as Taibai and Longbiao, which are all stunts for thousands of years." . Long Biao is Wang Changling, because Wang Changling was once a captain of Long Biao, so he was called Wang Longbiao.
Hu Yinglin means that both Li Bai and Wang Changling are superb in the creation of seven-character quatrains. However, by comparing the seven-character quatrains widely circulated, we can see that Wang Changling's works are more. Among Gong's frontier poems, there are two poems about leaving the frontier fortress, seven poems about joining the army, in my heart forever, in my heart forever, Poems about Long Xin Qiu, and Farewell to Xin Jian in Furong Inn, all of which have been handed down from generation to generation. The first of his "two dikes": the moon of Qin dynasty and the pass of Han dynasty, people don't return on the long March. If Wei Qing, who attacked Longcheng, and Li Guang, the flying general, were alive today, the Huns would not be allowed to go south to spend their horses in Yinshan.
Summary: Four sentences summed up the hardships and sorrows brought to the people by border wars from ancient times to the present, criticized the inaction of border generals and expressed their yearning for a peaceful life.
Concise language and rich connotations show Wang Changling's superb attainments in seven-character quatrains. No wonder later generations recommended this poem as the masterpiece of the seven-character quatrain in Tang Dynasty. From this point of view, Wang Changling has surpassed Li Bai in the creation of seven-character quatrains. Therefore, later generations regarded Wang Changling as the "seven unique skills".
