## 4 Experiment and Result
### User Study  
To investigate the role of the PCcGE in promoting couplet culture, enhancing user engagement, and its practical utility, we recruited participants and conducted a series of formal experiments. Before the experiment, we had implemented the corresponding system, where participants only needed to input their personalized needs, and the system would generate the corresponding couplets. **Experimental process:** First, prior to the experiments, we conducted a pre-survey across four dimensions to understand the extent of the couplet culture's dissemination and participants' backgrounds. The questions are shown in Table 4.  
Second, participants were asked to provide their personalized needs based on personal preferences and then use the system to generate four couplets. Third, after completing the experience, participants filled out a post-survey with questions evaluating the system across five dimensions. The questions are shown in Table 5.  
**Participants:** Since literary literacy is often correlated with educational background, we recruited 64 participants, including 16 undergraduate students, 16 master's students, 16 doctoral students, and 16 professors. We label the groups as _Pu_, _Pm_, _Pd_, and _Pp_, respectively. **Statistical Methods:** The surveys were conducted in the form of questionnaires. For the Likert scale questions (measuring degree of agreement or intensity), participants selected the statement that best represented their opinion, with scores assigned from 1 to 5, ranging from weak to strong agreement. For binary questions, a score of 0 was assigned for \"No\" and 1 for \"Yes\". The final score for each dimension was calculated as the mean of the total scores provided by the participants in each group. As per the experimental process outlined above, the pre-survey and post-survey results are summarized in Tables 6 and 7. We can ascertain the following from Table 6: Since couplets are an integral part of Chinese traditional culture, all participants were familiar with the basic characteristics of couplets due to their exposure to them during school education. However, approximately 88% of participants lacked the ability to create couplets. We also found that this ability correlates with the participant's generation and educational background.

\begin{tabular}{c c c} \hline \hline
**Dimension** & **Type** & **Question** \\ \hline Basic Knowledge & Binary & Do you know the basic features of Chinese couplets? \\ Ability & Binary & Do you have the ability to create couplets? \\ Related Experience & Binary & Have you used any other related couplet generation systems? \\ Interest Level & Likert scale & How interested are you in using a Chinese couplet generation system? \\ \hline \hline \end{tabular}
\end{table} 
Table 4: Pre-survey questions. The questions cross four dimensions to understand participants’ backgrounds. \begin{table}
\begin{tabular}{c c c} \hline \hline
**Dimension** & **Type** & **Question** \\ \hline Accuracy & Likert scale & How well did the generated couplets adhere to language rules? \\ Practicality & Likert scale & How well did the generated couplets meet your personalized needs? \\ Literary Quality & Likert scale & How creative and culturally rich were the generated couplets? \\ Engagement & Likert scale & How is the sense of participation in creating couplets? \\ Attractiveness & Likert scale & How effective was the system in enhancing the appeal of couplet culture? \\ \hline \hline \end{tabular}

Table 5: Post-survey questions. The participants filled it out to evaluate the system across five dimensions. tend to possess some skills of couplet creation, likely due to the prevalence of classical literature like couplets before the 1990s. In contrast, modern younger generations rarely study or create couplets, reflecting a shift in educational focus over time. This generational and educational disparity indicates a lack of couplet creation ability among younger people.
