The Dissemination Risks and Governance of Homophonic Double Entendres in High-Visibility Public Cultural Contexts:An Assessment of Socialist Spiritual Civilisation and Political Security Based on Subtitle Data from 'Treading Horses to Welcome Spring'

This paper employs the stage chorus subtitles displayed during the dissemination of ‘Treading Horses to Welcome Spring’ on short-video platforms as its sole empirical corpus. constructs an indicator-based assessment framework termed ‘Civic Determinacy–Communication Controllability (CD–CC)’. This framework aims to quantify the risk of directional instability associated with homophonic pun expressions within high-visibility public cultural contexts, without relying on motivational inferences or external speculative data. It further aligns and tests this risk against normative objectives in socialist spiritual civilisation development, online civility construction, and algorithmic recommendation governance. The methodology employs reproducible character-level counting and density metrics, normalising the repetition patterns of controversial trigger words within subtitles. CD and CC scores are derived through explicitly auditable English formulas. Results indicate: the subtitle text comprises 48 total characters (excluding spaces and punctuation), with the trigger term ‘treading horses’(踏马) appearing 4 times, yielding a trigger density (TD) of 83.333 per thousand characters; In the CD–CC scoring system, where TD serves as the core deduction metric, the Civilisation Determination (CD) score was 16.667 (0–100), indicating a significant structural risk of ‘high repetition of potentially misleading entry points’ in these subtitles. The author introduces the ‘text-structural controllability of dissemination’ indicator CC2 to circumvent the ceiling effect of baseline CC under single-subtitle conditions. This complements the literature dialogue on pragmatic ambiguity, pun-based rhetoric, and platform algorithmic diffusion studies, thereby enhancing construct validity and auditability.
