The"Shousu Party",a traditional event to commemorate the birthday of Su Shi,the great writer of the Northern Song Dynasty,was not only prevalent among the scholar-bureaucrats in the Qing Dynasty,but also promoted the emergence of the phenomenon of"celebrating birthdays"for other historical figures.The"Shousu Party"was first held by Song Luo,which seemed accidental on the surface,but in fact,it was a flower nourished by his lifelong efforts,which was inherently related to his admiration and love for Su Shi and his poems.The"Shousu Party"created by Song Luo could be widely accepted by later generations because it perfectly integrated the festive factors of birthday celebrations and was closely related to the growing poetic background of the"Song School"forces.
