The "Guimao Year" in calligraphy inscriptions cannot be written as "Guimao Year" because it is written in the order of branch years. "Gui" ranks last among the ten-day cadres, and "Mao" ranks fourth among the twelve branches. In the traditional calendar of China, the order of branches represents the replacement of years, so the years in the inscriptions must be written in the correct order of branches.
In addition, from the perspective of calligraphy art, the correct writing order can better reflect the professionalism and artistry of the works. Therefore, calligraphers will follow this rule when making autographs to ensure the integrity and professionalism of their works.
