Predominantly handwritten Chinese documents on printed police and judicial forms. At 38 pages, this is a comparatively substantial individual suicide dossier. It contains detailed police reconstruction, repeated witness interrogations, formal retention of the knife as physical evidence, judicial examination records, and a full medico-legal examination. The combination of the retained 小洋刀, the recorded throat injury, and the final finding of 自戕身死 provides unusually strong documentary evidence concerning the mechanism of suicide.

The extensive witness testimony explores Zhuang Yupeng's family, social, and personal circumstances before his death, but the surviving statements do not support reducing the suicide to a single clearly established motive. For catalogue purposes, it is therefore preferable to describe the contextual investigation without assigning a definitive causal explanation. The police death report appears to record the location as 黃山路784號, although the handwritten street name is somewhat difficult to read and should be treated cautiously.
