Ouyang Ping and his entourage also stood in Zong Guimin's room for on-the-spot observation, Mr. Ma's master bedroom and balcony did have a very thick two-layer curtain, when investigating the scene and the autopsy, everyone also noticed the curtains, at that time they just felt that the curtains were very luxurious and exquisite, but they didn't expect this layer.

In the end, Ouyang Ping had to pin his hopes on the residents of Building 6.

Tang Wenjun from No. 305 of Building 6 provided a situation (Unit 2 of Building 6, on the afternoon of the day of the crime, Tang Wenjun was the only person at home): Tang Wenjun worked in a chemical factory, and on the morning of the 12th, he fell asleep after returning home, and slept until more than two o'clock in the afternoon, got up and got up and put down a bowl of noodles, and after eating the noodles, he began to wash his clothes, and after washing his clothes, he ran to the balcony to dry his clothes, and when he was drying clothes, he saw Mr. Ma's niece Chen Qiming coming home from school. This should be the time when Chen Qiming disappears from people's eyes.

"Can you remember the exact time?"

"I don't know the exact time, it was the time when the students were out of school."

Tang Wenjun's words were not finished: "After about a minute or two, I heard a sound - the sound should have come from the bathroom of Mr. Ma's house - like the sound of an iron basin falling on the ground, I also glanced at the bathroom of Mr. Ma's house a few times, but unfortunately, I didn't see anything. Because the curtains in the window of Mr. Ma's bathroom are closed. ”

"Ouyang, in my impression, there seems to be a big iron basin in the bathroom of Mr. Ma's house." Liu Dayu said.

The author did not mention this large iron basin in the previous explanation. The reason why the author did not mention this big iron basin is because Liu Dayu and Chen Jie did not notice this big iron basin.

Afterwards, everyone went to Mr. Ma's house again, and there was a big iron basin in the corner of the bathroom.

"And after that?"

"After I got dressed, I started cooking dinner. After cooking, I simply ate a little bit and went to the night shift. Tang Wenjun said with regret, "At that time, I didn't think about it elsewhere, so Chen Qidi must have had an accident after I walked into the kitchen." ”

"How long did you cool off on the balcony?"

"The clothes were also washed on the balcony, about 40 minutes before and after. After the murderer killed Mr. Liu, he probably saw me washing clothes on the balcony, so he kept the cat at Mr. Ma's house. Tang Wenjun blamed himself a little, "If I don't sit on the balcony and wash my clothes, maybe Chen Qiming and Chen Qidi sisters can escape." ”

"Master Tang, you don't have to blame yourself, the Chen Qiming sisters must know the murderer - and may be very familiar, so it is very likely that the murderer is waiting for the sisters to come home at Teacher Ma's house."

"Master Tang, your family is so close to Teacher Ma's house, have you noticed that some time before the crime, especially a day or two before the crime? Have you ever noticed anyone who has entered Mr. Ma's house? ”

"I can only see the situation of Mr. Ma's house on the balcony, the key is that the curtains of Mr. Ma's house are closed all day long, so standing on the balcony of my house, we can only see the situation in the corridor outside Mr. Ma's house."

The corridor Tang Wenjun refers to is the aisle in front of Gate 205.

"If I'm not on the balcony, I can't see it. Yesterday afternoon, if I had been standing on the balcony, I would have seen the murderer. ”
