The downward percolation of birthday celebration customs， coupled with the gradual flourishing of popular cultural consumption， propelled the continuous prosperity of Shouxu （birthday congratulatory preface）寿序， shaping their stylistic characteristic as a medium for entertainment and diversion. Constrained by the celebratory atmosphere of birthday festivities and the psychological demands of secular culture， authors often struggled to exercise their full creative talents， causing the genre to fall into the ruts of formulaic tropes. In response， discerning literati upheld Guwen古文as the value benchmark and technical template. While establishing the works of Gui Youguang归有光as the orthodox model， they proposed multifaceted strategies to dilute the genre’s performative and social obligation， thereby elevating its stylistic quality and status. In terms of creative practice， these writers drew deeply from the experience of preceding genres. By expanding the scope for argumentation， narration and lyrical expression， they eschewed superficial tones in favor of enhanced intellectual depth and aesthetic resonance. Through the cumulative efforts of literati across different periods， Shouxu， originally a functional genre oriented towards the general public and specific rituals， transformed to some extent into a form of “scholar’s studio literature”. It even entered the purview of literary history， particularly the construction of canons， reflecting the persistent effort of elite culture to assimilate popular culture.
