Introduction to Longmen Tianguan

Dalongmen Castle was originally an important pass of the "inner edge" of the Great Wall in Ming Dynasty, and was known as the "throat of territory". According to the Notes on Water Classics, the Tang and Song Dynasties used to be called the "Holy City". It used to be a fortress town of the Central Plains and the Great Wall, and it was defeated repeatedly. In the Ming Dynasty, it was rebuilt as a military fortress. From Jiajing period, it was guarded by "Qin Gui, the commander-in-chief of Dalongmen", and it followed the Ming system until Guangxu period. The well-preserved Dalongmen Castle, the city gate and its surrounding military facilities can still make people see a complete ancient defense system, which fully embodies the outstanding architectural art and military talents of the ancient working people in China.

There are more than 30 cliff stone carvings on the cliffs on both sides of Longmen Gorge in the northwest of Dalongmen Castle, which are the original works left by the military attache stationed at the pass during the Ming and Qing Dynasties. Among them, "Wan Ren Tianguan" and "Forward Gong Li" are the most eye-catching, with a word height of 2.7 meters. The rest of the inscriptions vary in size, and the contents can be divided into two categories: one is to describe the majestic Guanshan Mountain, which is mostly regular script. The handwriting is vigorous and powerful, the brushwork is frustrated and powerful, and it is unique. The other is to describe the beautiful mountains and rivers here, so as to stimulate the patriotic enthusiasm of the military and civilians. This kind is written in running script and cursive script, which is a rare treasure. The inscription was written by Jia Sanjin, assistant minister of the Imperial Military Department, He Jiwen, Lu Zhiyuan and Wang Shixing, commander-in-chief of the Great Longmen during the Wanli period of the Ming Dynasty. These inscriptions provide reliable evidence for the study of ancient calligraphy. According to experts' research, it is the largest cliff stone carving group in northern China, and is known as the "historical and cultural corridor".
