Ouyang Ping brought Che Huating with him, and there was another very important reason: in Che Huating's impression, when the surnamed Ma first moved into No. 157 and made the bed, he once rolled up his sleeves and had a long scar above his right arm. Whether Yin Daping is "surnamed Ma" or not, Che Huating can not only identify the surname Ma from his appearance, but also identify the surname Ma by the scars on his arms and ground.

After dinner, Ouyang Ping and his entourage, accompanied by Xiao Zhang, investigated and visited a person, this person is Yin Daping's close neighbor, Ouyang Ping is Ouyang Ping, he is as careful as a hair, he thought of everything he should think of before doing a thing. Before Yin Daping is interrogated, these two issues must be resolved: first, the surname Ma has entered No. 157 twice, and in the two time periods before and after, Yin Daping's whereabouts may not be known to others, Yin Daping's neighbors should know, if the neighbors cannot provide accurate information, when necessary, they must have direct contact with Yin Feipeng and his wife; Second, who is the wife surnamed Ma? Neighbors and Yin Daping's parents should be able to provide some valuable information.

At about seven o'clock, two cars drove on Shou'an Road, and there were five people sitting on the first car, they were Ouyang Ping, Liu Dayu, Gao Jianguo, Luo Zirong and Xiao Liu; There were two people sitting in the second car, they were Yan Jianhua and Han Lingling.

The car stopped as usual in the square in front of Shou'anji Temple.

The group walked to No. 276 Guangming Street.

No. 276 is a courtyard, Xiao Zhang said, there are two tube buildings in the courtyard, and the Yin family lives in the first building.

Xiao Zhang did not walk into No. 276.

There was a small alley to the south of No. 276, and Xiao Zhang led everyone into the alley.

Xiao Zhang stopped at the gate of a house deep in the alley.

The door was opened by an old lady in her sixties.

The old lady is Director Peng of the neighborhood committee. Xiao Zhang wanted to ask Director Peng for help.

Director Peng readily agreed. She took the initiative to recommend a family, which was a door-to-door neighbor with the Yin family and was familiar with the situation of the Yin family.

In the end, it was the director of the neighborhood committee, and she had a clear eye for doing mass work, so she asked Xiao Zhang and his entourage to sit at her house for a while, and she invited people to her house to talk. This is very much to Ouyang Ping's thoughts.

This neighbor's name is Xu Haichu, and the two families share a corridor with the Yin family, because it is a tube building and there is no kitchen, so both families cook on the fire in the corridor. The other party knows how many people's meals are cooked and how many people eat at home.

Xu Haichu, who is about 50 years old, used to work in a vegetable farm, but after the market closed down, he rented a store and sold pork.

After Xu Haichu sat down, Luo Zirong handed him a cigarette and lit it with a lighter.

"Master Xu, we invited you here to learn about Yin Daping's situation."

"Ask! As long as I know. ”

"Is Yin Daping married?" Liu Dayu asked.

"It's over—but then it's gone."

"Left, when did this happen?"

"Didn't he go to jail? The next year, his wife left. ”

"Do they have children?"

"One boy, one girl. The boy left with his wife, and the girl stayed. This can't be blamed on Cui Fen - Cui Fen is Yin Daping's wife. ”

"Master Xu, what do you mean by that?"
