No need.
As for the issue of punctuation marks in couplets, there has not yet been a unified regulation on the couplets. As far as I know, some couplets do not add punctuation marks and only leave a space between the clauses of the upper and lower couplets to facilitate reading. Some couplets are added between the clauses of the upper and lower couplets but not at the end of the couplets, such as "The Complete Collection of Practical Couplets" ( Editor-in-Chief Chen Tulin). Some couplets have both Chinese and Chinese characters added at the end, such as "Selected Notes on Couplets of Past Dynasties". Whether the couplets should be marked with punctuation marks or not, I think, cannot be generalized and should be analyzed in detail.
1. Couplets that are hung or posted or combined with calligraphy, without punctuation. This is because there is no such traditional custom of couplets written with a brush. If you add punctuation marks, it will not only violate traditional customs, but also destroy the artistic beauty of calligraphy works.
2. Whether to add punctuation marks to the couplets in the couplet depends on the needs.
Add punctuation marks to help clarify the meaning. Couplets are the same as other literary styles. In order for readers to correctly understand the meaning of the couplets, punctuation marks must be added.
For example:
The world-famous "Sanchakou";
The astonishing masterpiece "Cross Slope".
This is an inlaid couplet praising the famous Peking Opera artist Gai Jingtian (Gai: real name Zhang Yingjie). "Sanchakou" and "Cross Slope" are his representative plays. If the book title is not included, , it is not easy to understand for some young people or those who lack opera knowledge. Others that fall into this category include:
There is no female dog in the Book of Rites, and there is a male dog in the Spring and Autumn Annals.
"The Day of Changes" says: The universe is fixed,
"Mao Shi" says: "Zhonggu music".
