For the sake of future generations, Xisai Mountain Beifeng Mountain built a beautiful antique pavilion, named "North Wang Pavilion", where you can overlook the river Tao rushing east, overlook the greenery of Sanhuazhou and Cehu in the north of the river. Standing on the north Wang Pavilion, watching the Youyou River; A leaf boat, dotted with blue waves, spread layer by layer. This situation, this scene, can not but lead to the quiet feeling of thinking about the ancient, silently reciting Liu Yuxi "Xisaishan Huaigu" God's pen: "Wang Qianlou ship down Yizhou, Jinling Wang's temper is sad. Qianxun iron lock sinks the river, a piece of stone falls out. The past has been hurt several times in the world, and the mountain shape is still cold. From this day four seas as home day, so let Xiao Xiao Lu Qiu. Standing on the north Wangting, you can really read Liu Yuxi's mood when he recited "Xisai Mountain Huaigu", and understand the praise of future generations for this poem "like deliberation, whether it is written on paper, God comes to the sky". But at this moment, looking westward at the North Pavilion, the whole city of Yellowstone is covered in a gray smoke.
