Lanzhou in Song and Yuan Dynasties had dense forests and beautiful scenery. The vegetation in Lanzhou in the Ming Dynasty was also very good. From the Ming Dynasty to the mid-Qing Dynasty, Gaolan Mountain was once a place with dense forests. In the third year of Hongwu in Ming Dynasty (1370), the ruins of Lanjun County were rebuilt: "There are more than 83,000 pines and cypresses in this mountain".
"... very green immediately understand, Shandong even GuanZiQi, Hebei note (cloud cold. It's sunny and thousands of trees row high waves, and the double bridge pillow is blue with the setting sun. I saw that there was a war in ancient times, so I called Yao to visit Korea. "This is the poem Gao Lan Shan Fu written by Zhou Guanghao, a poet in the Ming Dynasty. This poem records the vegetation of Gaolan Mountain.
By the early Qing dynasty, the vegetation in Lanzhou had not been greatly damaged. Today's Gaolan Mountain, Shuimogou and other places are still densely forested. Qin, a poet in the Qing Dynasty, wrote in his poem "Shuimogou": "The giant gate rushes into the ditch, and there are green hills on both sides. At the corner of Pinggang Bay, Chai Heng is seen in the shadow of the poplar trees. "
Gaolan Mountain Gorge is said to be the place where Liu Bowen beheaded Long Mai. The legend of Liu Bowen's beheading of Long Mai is actually a reflection of the tense situation in northwest China in the early Ming Dynasty.
People think that since Liu Bowen beheaded Long Mai, the geomantic omen in Lanzhou has been bad. Since the Ming and Qing Dynasties, there have been few high officials in Lanzhou. The highest official position is just the history of the Ministry of War, and there is no top academic master. Therefore, people built three pavilions (Kuixing Pavilion) on the top of Gaolan Mountain to gather the Lanzhou context.
"After the Ming Dynasty, China's economic center moved south, and the Oasis Silk Road declined completely. The decline of economy will inevitably lead to the decline of culture! " Kim Yu Ming said.
