In Qiandao eight years, the Southern Song Dynasty poet Lu You came to Qingshanguan. At that time, the country was on the verge of peril because of Jin invasion, he suggested to resist Jin. Lu You was invited to participate in the recruitment as a officer and judge by general wangyan who was from Sichuan. At that time, Xuan Fusi was located in Nanzheng, which is the front line to resist Jin.
In autumn that year, as the military affairs, Lu You went out from Nanzheng (now Langzhong), Langzhong, it had been dark when he came to Qingshanpu. While he saw the leaves all over the ground, the post was old, desolate and dilapidated. He knew this is a microcosm of the national war, so he wrote two poems“Taixi. Written in Qingshanpu”with a long sigh.
After Lu You left Qingshanpu, no matter where he went, Qingshanpu and Taixi poems are always lingering in his mind.
