The setting sun in autumn penetrated the large criminal police office through the glass window and reflected on the ground, forming a scratch of light and shadow. I stood up from the computer and gave a newly typed "Case Investigation Report" to Captain Nan Sidao who was in the office for review. Nan Sidao was looking at a dossier attentively at this time. "You seem to have been studying this case file all day?" I pointed to the file that Nan Sidao was holding in his hand and asked, "Are there any doubts about this case?" "No, no, you know that this case has been closed and the criminal has been punished as he deserves." Nan Sidao put out the cigarette butt, put down the file in his hand, took my investigation report and said, "I just want to find some patterns in the criminal record of this habitual thief."
