Before Ran Shijie came to Ran Shimei's house to call the door - around three o'clock, the cat barked twice, the door rang twice, and the door was opened by a person? Or is it driven by two people? Why do you need to wait for half a cup of tea in between?

What's the mystery here?

According to Ran Shimei, about half an hour before Ran Shijie knocked on the door of Ran Shimei's house, there should have been a cat meow and the sound of opening the door - or closing the door, isn't Ran Shijie worried about his father's body? When he found out that his father's body was abnormal, he hurriedly ran to the backyard to inform his brother Ran Shixiong and sister Ran Shimei. However, Bao Peizhu's mother and Xie Xiaoman did not provide relevant information. Therefore, the opening of the door at around three o'clock, or the sound of closing the door, is likely to be made by Ran Shijie, and it may not be Ran Shijie alone who alarmed the cat.

Judging from the information provided by Bao Peizhu's mother and Xie Xiaoman, at about three o'clock in the evening of January 28, accompanied by two cat meows, there must have been one or several ghosts wandering in the Ran family's compound.

Combined with the information provided by Liu Pang and Mrs. Gao, the time of Ran Ruzhai's death should be after three o'clock, don't forget, when Liu Pang dressed Ran Ruzhai, Ran Ruzhai's limbs were already stiff, so it can be inferred that Ran Shijie knocked on the door of Ran Shimei's house at half past five o'clock, which is very likely to be shown to others in the backyard of Ran's house.

Regarding the opening of the door - or the sound of the door closing, Xie Xiaoman said casually, if it is a directed reflection and memory, what will the situation be?

"Sister-in-law, we want to know which school your daughter Xie Xiaoman is studying in?"

"It's at Mafu Street Middle School."

"Mafu Street Middle School is just north of the street corner -- it's two or four or five hundred meters away." Director Zhang said.

"What time does the first class start in the afternoon?"

"One hour forty." Xie Yao pointed out. This was the first and only sentence Xie Yao said.

Ouyang Ping rolled up his sleeves and looked at his watch, the time was one twenty.

"Let's go, I'll accompany you to the school, Xiaoman's first class in the afternoon is physical education, just ask the teacher for a leave." Li Dahong said.

Li Dahong can take the initiative to cooperate with the work of the police, which is Ouyang Ping's satisfaction and gratification.

The group walked out of the backyard of Ran's house, walked out of Hoop Barrel Alley, and walked all the way to the street.

Everyone followed a few students to the entrance of the school.

Wei Zimin said a few words to the doorman, and then led everyone into the gate of the school.

On the east side of the boulevard there are several table tennis tables made of bricks and concrete, all of which have students playing table tennis, and there are many people standing on either side of the table.

Li Dahong walked up to Ouyang Ping: "You wait for us in front of the table tennis table, I'll call Xiaoman, and ask their teacher for a leave by the way." Li Dahong said as he walked towards the teaching building.

The class bell suddenly rang in the schoolyard, and the students who had been playing in front of the table tennis table scattered in a hurry, three in groups, five in a group, and ran towards their respective classrooms.

After about two minutes, Li Dahong led his daughter Xie Xiaoman to the table tennis table.

"Have you taken a leave of absence from your teacher?" Ouyang Ping looked at Xie Xiaoman, who was a little restrained.

"I've taken a leave of absence." Xie Xiaoman flashed a pair of big eyes, and rubbed the corners of the red down jacket with both hands.

"Xiao Man, tell the police uncle again what you just told me." Li Dahong encouraged her daughter.
