Cultural relics value of thirteen products in Shimen

Thirteen products of Shimen, commonly known as "Thirteen Products of Han and Wei Dynasties", are precious historical materials for studying the traffic jam and water conservancy construction of the inclined plank road in Hanzhong, and are also masterpieces of calligraphy art. The stone carvings in Shimen, Hanzhong are in an important transition period from Chinese characters to seal script, which represents an important stage in the history of China's calligraphy development. These stone carvings reflect the development process of Chinese characters from seal script to official script and from official script to regular script. They are the historical traces of the development of Chinese characters, from which we can see the historical track of the evolution of China's calligraphy. Since the war at the end of Qin Dynasty, Liu Bang was named Hanwang by Xiang Yu, "Wang Ba, Shu, Hanzhong and Nanzheng (now Hanzhong)" (Historical Records). Based on Hanzhong, Liu Bang established Sanqin, destroyed Xiang Yu and established the Han Dynasty in the name of "Han". From then on, they were called "Han people" and "Han people", China's calligraphy style was also called "Chinese characters", and China's culture was called "Chinese culture".

At the same time, it is also a physical specimen to study the calligraphy of Han and Wei Dynasties, which has inspired and promoted the development of China's calligraphy art. Up to now, there are still a considerable number of stone carvings and calligraphy cliffs in Shimen, Hanzhong, and 1000 has been praised by scholars in past dynasties for more than years.

In the fifth year of Guangxu (1880), Shimen stone carvings were introduced to Japan through Yang Shoujing, which was greatly appreciated by Japanese calligraphers. Many Japanese calligraphers buy Shimen Cliff rubbings for research, which are listed as "compulsory classics" for learning calligraphy. Up to now, Japanese calligraphy circles still give high praise to the stone carvings on the cliff in Shimen, Hanzhong. Kang Youwei praised the Shimen cliff. He divided the ancient famous stone carvings into six grades: first, divine, second, exotic, third, fine, fourth, fine, fifth, first and sixth, among which only three stones were listed, and Shimen Ming was one of them. In the 1940s, the photocopy of Ode to Shimen was reprinted many times. Dr. Sun Yat-sen and Mr. Yu Youren, the master of calligraphy, also highly admire Shimen calligraphy.
