Bao Chengxian's poems

The big three passes, also known as the three passes, are one of the four passes in Guanzhong. Located in the northern foot of Qinling Mountain, more than 20 kilometers south of Baoji City, Shaanxi Province, it is located on the scattered ridge of Nanda in Baoji County, Shaanxi Province, and has been the "throat of Sichuan and Shaanxi" since ancient times. In the past, the Big Three Pass was the pass of a great master, which was to "focus on the door, close to the huge pier, and build a series of buildings to worship Wei". It locks the Chencang ancient road, which is really "the road is as dangerous as Shushan, and the gas increases Qin Dixiong". It can be attacked and retreated, and it is a battleground for military strategists in past dynasties. It is a battleground for military strategists in past dynasties. In the Song Dynasty, the nomads from the army went south and invaded Shaanxi and Sichuan. During the Song Dynasty, Wu Jun and Wu Lin gathered their forces, seized the danger, held on and repelled the nomads from attacking many times. Now it's closed, the ruins of the city exist, Sichuan-Shaanxi Highway and baoji-chengdu railway all pass through here, and the natural barrier has become a thoroughfare. The words "ancient three passes" carved on rocks by predecessors have yet to be verified. When Chu and Han contended, Han Xin "built a plank road to hide the truth" passed through here; During the Three Kingdoms, Cao Cao made a Western Expedition, and Zhang Lu also passed through here. According to Chen Shou's "The Three Kingdoms", "In the spring of the sixth year of Jianxing, Liang Huiguan surrounded Chencang, but Cao Zhen refused ..." Especially in the first year of Shaoxing in the Southern Song Dynasty (11), the Wu brothers fought fiercely with the nomads from here, and Jin Wu only escaped. Later, in order to commemorate the Wu brothers, Wu Gong Temple was built in Kansai, and there were portraits of the Wu brothers in the temple. There is a stone tablet of "Ancient Great Three Passes". Today, on the rocks of the Sichuan-Shaanxi Highway, there are several big characters carved by predecessors: "Ancient Great Three Passes". The mountains here are steep and mountainous, and there is a tendency of "one person defends it, and ten thousand people can't force it". Today, there are ancient ruins of Sanguancheng, Waterfall Mountain and Figure-8 Panshan Road on the northern slope of the Qinling Mountains in baoji-chengdu railway, which are magnificent.

The Big Three Pass is an important pass in the westernmost part of Guanzhong, and it is also a symbol of the wildness of Guanzhong River culture, Qinba culture and Longxi culture. At the same time, the name of militarization also emphasizes another meaning beyond the geographical division of the three customs. In the Northern Song Dynasty, Yue Jiajun fought bravely against the soldiers of Jin Wushu here. The land tour in the Southern Song Dynasty made Sanguan famous in one fell swoop, and vividly expressed the heroic spirit of ice and snow in the frontier with the poem "Iron horse and autumn wind scattered customs". Since then, the Big Three Pass has become the most masculine carrier in China people's minds and the ultimate dream of countless heroes for thousands of years.
