What is the origin of Jianmenguan?

When Zhuge Liang built the Shu Road in the Three Kingdoms, he saw that the terrain here was steep and there was a natural pass between the two mountain canyons, so he built checkpoints and thought it was a barrier between Shu and Han. After Zhuge Liang's death, Jiang Wei led his troops here to resist Wei Jun, a hundred thousand of Zhong Hui, until he surrendered to Wei.

The modern Jianmenguan building was rebuilt in 1980s. It was rebuilt after being destroyed by fire in 2005. After being destroyed by the Wenchuan earthquake in 2008, the Jianmenguan building was built on the site of the Qing Dynasty.

In the ninth year of Qin Huiwen (3 16 BC), Sima Cuo destroyed Shu, which was the way. According to legend, during the Warring States Period, King Hui of Qin wanted to swallow Shu, but there was no way to enter Shu. He lied about giving Wang Wu a beautiful woman and a hardware cow.

King Shu believed it, and sent five Ding Lishi around him to clear the way, enter Qin to marry beautiful women and transport Taurus, and then opened this Shu Road, which is called "Jinniu Road", also known as Jianmen Shu Road. In the fourth year of Yongping in the Eastern Han Dynasty (AD 6 1), Yang Jue, a captain of Li Si, repaired Jianmen Shudao.

During the Three Kingdoms period, Zhuge Liang, the prime minister of Shu and Han Dynasties, took Hande County (now Hanyang Town) as a place where "Dajianshan is 30 miles from Xiao Jian Pass, and even the mountain is in danger". Here, "the cliff of Dajianshan interrupts the intersection of two cliffs, builds stones on the cliff as a door, sets up a pavilion commander and a garrison, and becomes a military pass.

Since the Sui Dynasty, Shaanxi and Gansu have entered Shu, diverted from Meng Jian County to Niutou Mountain, and passed through the desert tree (known as the desert tree by the people), reaching Jianmenguan. The pavilion road from Xiao Jian to Dajianguan has been gradually abandoned, and the name "Jiange Road" has become another name for Jianmenguan.

Therefore, the names "Jiange" and "Jianmen" used in many historical books from Tang Dynasty to Qing Dynasty all refer to Jianmen Pass. In the second year of the Republic of China (19 13), after Jianzhou was changed to Jiange County, "Jiange" only referred to the county name.
