The signatures of banners and couplets are generally written in the lower right corner of the first couplet, such as "XX Shu Ya (back to the village)", while the specific year, month, book, seal are written in the lower left corner of the second couplet. When arranging composition, we should pay attention to the primary and secondary relationship between words and inscriptions, and also pay attention to the natural vividness and patchwork of words and inscriptions when creating. At the same time, whether in banner couplets or other forms of calligraphy works, inscriptions should avoid usurping the role of the master, so as not to affect the overall artistic effect.
