Whether a city is an ancient city with a long history can be seen from the frequency with which it appears in ancient poetry. The land of China has a long history, and many cities have a history of thousands of years. And the names of these cities, and the poems that have been sung for a long time, have long been condensed together, and each other has achieved each other's glory.

For example, Su Shi's "Hunting in Mizhou" has made today's Shandong Zhucheng go to the world; for example, Yang Wanli's "scenery is not the same as the four hours", embedding the West Lake of Hangzhou in poetry and singing from generation to generation; and Li Bai's sentence "The Yellow Crane Tower of the Late Man In the West", which has made Wuhan, Hubei famous.
Those cities, those poets are very famous, and today, we see a couplet, let's guess, which city is this written about?
"Lotus flowers on four sides, willows on three sides, a city of mountains and half a city lake".
First of all, since there are "lotuses" and "willow trees" in the couplet, it shows that there are not many waters in the city. In the second half of the sentence, "a city of mountains and half a city lake" indicates that this water is a "lake", and there is also a mountain.
A city with a long history, and mountains and water, then the range of options will not be too wide. First of all, the lake, the most well-known should be the West Lake and slender West Lake, one in Hangzhou, one in Yangzhou, but in these two cities, the lake is too famous, the mountain can not say no, but there is always a distance from the mountain in our impression.
And these two couplets come from the Canglang Pavilion of Daming Lake in the Qing Dynasty. Since Daming Lake has appeared, then this city is easy to guess, that is, Jinan City. And that "one city mountain color" naturally refers to the Thousand Buddha Mountain in Jinan City.
The meaning of these two couplets is that the lotus flowers and willow trees on three sides around Daming Lake are extremely beautiful, and Daming Lake seems to reflect half of the mountain color of Thousand Buddha Mountain.
As the capital city of Shandong Province, Jinan has many scenic spots, such as Baotu Spring, Thousand Buddha Mountain, Black Tiger Spring and even Hongye Valley, which are very famous scenic spots. As a famous historical and cultural city, Jinan City also has many historical stories, which have also influenced the literary creation of poets here.
For example, the famous "Jinan Er'an", one is Yi'an resident Li Qingzhao, and the other is the Xin abandonment disease of You'an, and the status of the two in the history of Song Ci cannot be shaken. In modern and contemporary literature, Lao She's "Winter in Jinan" has popularized the beauty of Jinan for us.
Remember that classic sentence? "The best thing is that it snows a little..."
