Public information about Zhang Run is limited. The works held in the library, nine in total, concentrate on legal practice and accessible legal education. Judging from the representative titles, the subjects closely follow everyday legal needs: annotated provisions of the Civil Procedure Law, illustrated standards for case filing, evidence, conviction and sentencing, interpretations of the Public Security Administration Punishments Law, and guides to housing expropriation and compensation and to road traffic safety law, along with one-stop legal guides on labor disputes and on housing demolition, compensation and resettlement. The author also wrote Network Marketing. The writing emphasizes combining statutory annotation with practical operation, and uses diagrams and case-based explanation to lower the threshold of understanding, serving general readers and grassroots legal practitioners; the titles are mostly classified under law, with some under social culture and management.
