Let's take a look at Ouyang Ping's situation along the way.

On the way to the backyard of Ran's house, Wei Zimin called Director Zhang by the way, and with Director Zhang as a guide, the investigation would be much more convenient.

When the group walked into the backyard of Ran's house, the time was twelve thirty-five, and Ouyang Ping stepped on it.

Both 187 and 188 had people at home. No. 187 is Director Chen Guoquan's house, we have explained the situation of Director Chen's house before, and No. 188 is Xie Yao's house.

Because of the cold, the doors of both houses were closed, but the doors were not locked.

When Ouyang Ping and Director Zhang walked into the aisle, they could still hear the voices of people talking inside doors 187 and 188.

Director Zhang knocked three times on the door of Room 187.

It was Chen Guoquan's mother-in-law who opened the door: "It's Director Zhang!" What's wrong? ”

"Old sister-in-law, these comrades are comrades from the Municipal Public Security Bureau, and they want to know a little bit about the situation." Director Zhang said as he looked into the room, there were three people sitting at the dinner table, two sixteen or seventeen-year-old children, and a woman in her forties, her name was Bao Peizhu, and she was Chen Guoquan's wife.

Bao Peizhu saw a few uniformed people standing at the door, and stood up to greet her.

"Auntie, you eat first, and after eating, we'll talk." Ouyang Ping said.

"Eaten—eaten, ready to clean up. Come in - come in. The old man greeted everyone warmly.

Bao Peizhu gestured with the two children a few times and began to clean up the dishes and chopsticks.

The two children went upstairs.

A minute later, the large table was cleaned up.

Soon after everyone sat down, Bao Peizhu brought a few cups of tea.

Ouyang Ping didn't just come to the door this time for the gray button.

"Auntie, sister-in-law, sit down and talk."

Bao Peizhu brought two round stools from the inner room and sat down with her mother-in-law.

Wei Zimin closed the door.

"On the morning of January 28th, did you hear a knock at the door next door?" Ouyang Ping lowered his voice. Ran Shimei's house and Chen Guoquan's house are only separated by a wall, and the sound is a little louder, and the next door can hear it.

"I hear you." The old man whispered.

"The people in the courtyard heard it." Bao Peizhu said.

"Who knocked on the door?"

"It's the third master of the Ran family."

"Do you remember the time of the knock?"

"Very little." Bao Peizhu said.

"The relationship between the couple is not very good." Mother said.

"Do you quarrel a lot?"

"Never quarrel. The couple slept in separate beds - it had been a few days. ”

"It's more than five o'clock, and it's almost dawn." Bao Peizhu said.

"I'm getting up to make breakfast." The old man said.

"My mother gets up at half past five every morning to make breakfast." Bao Peizhu added.

"What did Ran Shijie say?"

Both mother and daughter were silent for a while.

"It seems to say that the old man is not doing well." Mother said.

"There is another sentence, which is to tell Ran Shimei to hurry to the front yard." Bao Peizhu said.

"Did he say that Ran Ruzhai was dying?"

"No, if he says that Ran Ruzhai is dying, we will definitely rush over immediately."

"On the first night, did Chen Erhu drink?"

"Yes, Chen Erhu is drinking, the night before, Ran Shimei went to the street to buy half a salted duck and fried a few dishes."

"Does Ran Shimei often cook delicious dishes for Chen Erhu to drink?"
