Thankfully, among the tenants, there was only one outsider with the surname Ma - the others were locals - and this person had moved in again since the first wall had been built before Chen Hongmei moved into 157, let alone the surname Ma. Previously, everyone had excluded this person, but this time, the comrades excluded him as usual, and the reasons have already been explained before, so I will not repeat them here.

Between half past nine and nine fifty, all the tenants who had lived in No. 157 walked into No. 157 one after another, and when Zuo Xiangdong and Director Gu went to Fenghuang West Street to invite Chen Hongmei, Director Gu had already sent out three household registration police.

The tenants who walked into No. 157 one after another were Zhang Guangnan (renting two wings in the east), Gong Caiju and his husband (renting two west wings), Wang Zhongkui (renting two south wings in the east), and Zhao Mingyue (renting two west wings).

Ouyang Ping took out the names of the above tenants from two pieces of paper and wrote them on the other paper, and the content in parentheses was made by Ouyang Ping, so that the key objects of the conversation were clear at a glance. Ouyang Ping also drew a circle on the names of Zhang Guangnan and Wang Zhongkui.

Considering that there is a vacancy in the process of renting out the house at No. 157, Ouyang Ping specially asked four people about this issue (Ouyang Ping also specifically asked about the time of renting), and the following are the answers of the four people (please note that the inquiry was carried out separately):

Zhang Guangnan: "When I lived in No. 157, there was a family living in two wings in the west, the man's surname was Gao, the woman's surname was Gong, the man rarely spoke, the woman was in charge, I called her sister-in-law; I moved into No. 157 at the end of May, and I moved out in August or September, but I can't remember the exact time. ”

Zhang Guangnan's answer is basically consistent with the information provided by Che Huating, the only difference is the time when Zhang Guangnan moved out, the time provided by Che Huating is September, and Zhang Guangnan said, "It's either August or September." ”

Ouyang Ping excerpted the information provided by the two people in his notebook for easy comparison.

After Ouyang Ping questioned Gong Caiju and his wife, he found another problem: Gong Caiju's family moved into No. 157 in June 1989, and before that, no one lived in the two West Wings (Gong Caiju particularly emphasized: she will not be mistaken, because her memory is particularly good,)

When Zhang Guangnan lived in No. 157, there was obviously no one living in the west wing, why did Zhang Guangnan say that there were people living in it? Was it because it was too long for him to remember, or did he say it on purpose?

"We heard that there was a large pile of bricks in the courtyard of No. 157, and the pile of bricks was not there when your family moved in."

"Yes, in addition to a pile of bricks, there are some small tiles." Zhangguang South Road.

"Was that pile of bricks still there when you moved out?"

"Yes, definitely, a few days before I moved out, two bricks fell off the stove in the kitchen, and I picked two full bricks on top of the pile of bricks -- and fixed the stove."

In the above materials, there are only two people who have lived in the east wing, and only Zhang Guangnan has lived in the north wing.

After questioning Zhang Guangnan, Ouyang Ping and Yan Jianhua took a special look at the hole in the wall where the body was found, and what Zhang Guangnan said was right (about bricks), most of the bricks used in the first wall were broken bricks.
