According to Liu Heng’s pref., this short work is the edited transcript of conversations with visitors who came asking for clarification on certain points discussed in Yongli yongyan (q.v.), and then wrote down his answers. It presents itself as a collection of miscellanous commentaries and advice for local officials, based on Liu Heng’s experience as a magistrate and prefect in Sichuan between 1827 and 1829. The entries are arranged in no particular order and cover a wide range of topics, with particular emphasis on the procedures for interrogating suspects accused of a crime or an offense. Other topics include charity for the poor, control of corrupt clerks, the moral and practical duties of officials, and the legal and customary norms concerning customary fees. Zhuo Bingtian’s pref. suggests that both Dulü xinde and Shuliao wenda were printed for the first time in 1837.
