"Mix some hair in the lime, and the mud won't crack after it goes up, which is the same as the country people mixing straw into the mud to build walls." Su Yingqing said as she walked into the kitchen, "Director Gu, take a look-see if there is any hair in the lime?" ”

Director Gu, Ouyang Ping, and Liu Dayu lowered their heads and bent down to look at the lime layer that had been pried open, and there was indeed hair stubble in the lime.

Zhang Guangnan took out a pack of Jin Jingnan from his pocket, poured out a few, handed one to one person, and then lit everyone's cigarettes according to the lighter, and when he lit Ouyang Ping, he said in a low voice: "Captain Ouyang, can I go?" ”

Ouyang Ping took two puffs of cigarette, and then said, "Please wait a moment, please help us recall." Ouyang Ping said as he walked towards the living room.

Zhang Guangnan and Su Yingqing followed, and the others followed.

Ouyang Ping walked into the east and north wings: "Zhang Guangnan, at that time, which room did you sleep in?" ”

"This is it." Zhang Guangnan said without thinking.

"How do you make your bed?"

"The bed is made against this wall."

It is consistent with Chen Hongmei's paving.

"Is the head of the bed against the window?"

"That's right!"

"Could you please remember that the place where the wall meets the window is where it is now?"

Zhang Guangnan walked to the corner of the wall, looked at it carefully, and then measured the width of the north wall with the index finger and thumb of his right hand—that is, the width of the brick wall on the east side of the window: "The current appearance is the same as when I lived here, and this wall is only so long. Zhang Guangnan stretched his index finger and thumb as far apart as possible.

Zhang Guangnan's statement is consistent with the statement of Che Lao's wife.

"Look -- there -- there's a visible scratch on the ceiling."

Everybody saw it -- this was the second time everybody looked at the scratch.

"When I moved in, the scratch was in this location. Usually lying in bed, as soon as you open your eyes, you can see this scratch. ”

Zhang Guangnan's statement is consistent with Mao Dawei's statement.

In other words, this wall existed before Zhang Guangnan lived in No. 157.

The nets continued to be retracted, and the area of the water shrank by a large circle.

Zhang Guangnan said that there are noses and eyes, and there are well-founded, but everyone can't help but believe it, of course, this is also what Ouyang Ping wants, isn't the process of solving the case just stripping away the cocoon, removing the false and retaining the truth, and taking one from the other.

Disappointment and hope coexist.

"Zhang Guangnan, I'm sorry for delaying your time, thank you for your cooperation and assistance, Master Su, thank you too!"

"It's okay, just figure it out, it's not easy for you!" Zhang Guangnan was originally a little resentful, but now, he finally said a word of relief to the comrades.

After sending Zhang Guangnan and Su Yingqing away, Ouyang Ping took out his notebook from his pocket. The same content was presented in front of Ouyang Ping's eyes again, because this content was very important, we had to present it again:

Zhang Guangnan, age: about 47 years old, rented two east wings from May to September 1989; Current address: Work unit: Qixingmen Post Office.

Gong Caiju, age: about 50 years old, from June to August 1989, rented two rooms in the west wing; The current address is unknown, but you can find out the situation with the middleman Li Tailor - this tenant was introduced by him (Li Kee Tailor Shop, No. 234 Chung Wo Street); Housewife.
