In the summer of the fourth year of Tang Tianbao (AD 745), 34-year-old Du Fu came to Jinan and attended a banquet organized by officials and celebrities in Lixiating. The most distinguished guest at the banquet is Li Yong, the county magistrate of Beihai, whose articles and calligraphy are world-famous. Celebrities gathered gracefully and enjoyed the banquet. Du Fu immediately wrote a poem "Banquet with Li Beihai in the Pavilion": "Jujube covers in the east and Lingqinghe in the north. There are many celebrities in Jinan. Yunshan has flourished, and Yu Pei is still singing. Pruning bamboo is not affected by summer heat, and exchange air surges. What a pleasant meeting, what will happen to the sunset! Both the noble and the humble are in service, and it is even harder to go from the public. " Just as Mount Tai is proud of Du Fu's poem "Reach the Peak, the other mountains all appear dwarfs under the sky.". There is no doubt that the famous Lixia Pavilion in Jinan is also good at Du Fu's poem "The sea is here, and there are many celebrities in Jinan". According to experts' research, Du Fu's travels in Shandong in those days have been roughly sorted out: Du Fu's father, Du Xian, was a Sima in Yanzhou, and his younger brother, Du Ying, was the main book in Linyi, qi zhou. The combination of mothering and roaming, Du Fu traveled to Shandong twice in his youth, leaving ten poems in Tai 'an, Jining and Jinan today. Among them, he wrote three poems in Jinan. Coincidentally, these three poems are all written in pavilions to express his feelings, and all have the word "pavilion" in their titles. Du Fu's "three pavilions" in Jinan are Lixia Pavilion, Garden Pavilion and Queshan Lake Pavilion. The latter two pavilions no longer exist today, but the Lixia Pavilion has existed for thousands of years. "Looking back in the pavilion and watching chess under the bridge", today's Lixia Pavilion is a unique symbol of Jinan, the spring city.
