What movie is death at six?

The film "Blood Splash on the Screen" was directed by Qicang Zhang, produced by Xi 'an Film Studio, starring Sun Zhongliang, Qian Wen and Wang Wensheng, and released on 1986. This film is based on four screens in Gao Luopei's book Di Gong Case in Tang Dynasty.

The film tells the story that Di was promoted to Puyang secretariat by Pengze county magistrate and went to Yunzhou to say goodbye, which coincided with the murder of Ke Xingyuan, a businessman in the state. Tengkan, the secretariat of Yunzhou, entrusted Di to investigate the case due to illness. During the interrogation of Di Renjie, Teng Kan's wife was killed. When the two cases crossed, Di Renjie finally not only thoroughly solved two murders, but also exposed Teng Kan's hypocritical face and gave him a moral trial.
