What is written on the left and right sides of the wrong calligraphy work?

Signed it. Calligraphy works are written from right to left, and the one on the right is called the upper paragraph. Generally, the above paragraph clearly shows the theme of the text in other fonts, while the next paragraph can clearly show the creation process, feelings, creation year, time, address, fasting number and so on. Most couplets can be written. The first paragraph of the couplet mainly talks about why people and activities do this. If it is the main hall, vertical shaft and other works, generally do not write, are explained in the next paragraph. The next paragraph is often called a signature.
