This plaque was inscribed by Xiao Xian, a famous calligrapher in Ming Dynasty. Its plaque is more than 5 meters long and 1.5 meters high, and each word is more than 1 meter, which is very large; It gradually increases from east to west, and in stroke processing, the first word "first" is rewritten into the first word of cursive script, which reduces the number of strokes.
The reduction of visual components makes the strokes of Guan more dignified and powerful. Draw people's attention to the word "Guan" and highlight that "Shanhaiguan" here is the first pass in the world.
