There are two formats for writing signatures in hard-tipped calligraphy, and the signatures are also different.
1. When written vertically, it should be written from right to left. The signature "XX Letter in the Autumn of Year Yiwei" is also written vertically, on the far left side of the work. Remember that the upper and lower parts cannot exceed the main text.
2. Write horizontally, in line with modern habits. The signature should be written on the bottom line to the right, but the last part should not exceed the main text content above.
The time is generally based on the lunar calendar. For example, this year is the year of Dingyou (the Year of the Rooster), and October 8 is the eighth month of the lunar calendar. The signature can be written as: Wang Xizhi's book in Zhongqiu of the year of Dingyou.
