Shen Jiaben’s postf. states that Shen Zhongwei was active under emperor Shundi of the Yuan (r. 1333-67). Fu Lin’s original “rhymes” are followed (in the fullest cases) by an explanatory commentary (疏解) based on Tang lü shuyi 唐律疏議, followed in turn by a “straightforward explanation” (直解) and “comparisons of terms” (語較), then again by substatutes (通例) selected from current Yuan legal usage. According to Yang Weizhen’s pref., the aim was to revive Fu Lin’s teaching, viz. interpret the law taking account of changing circumstances. Shen Jiaben notes some interpolations in the text attributed to Fu Lin, as well as obvious errors in the quotations from Tang lü shuyi. Still, according to Langlois (see under Xingtong fu), this is the best extant commentary to Xingtong fu (q.v.).
