"There were books in the bag, and I was worried that the rain would wet the books, so I used an umbrella to block the top of the bag. Naturally, the top of the bag is not wet. ”

"If it is true as you say, the front hem of your down jacket will not be wet, it should be your back, but not a drop of rain will fall on your back."

The old couple's eyes swept over their son's down jacket, and they should have understood something.

"I don't understand what you're saying, why are you always going around in circles?" Li Dongting played the trick of pretending to be stupid.

Ouyang Ping ignored Li Dongting's words, and still walked forward according to his own ideas: "On the surface, you are preparing for class, but your preparation notes are from 1993 to the second semester of the 1994 school year. Tonight, you didn't write a word on this preparation note, maybe you don't believe it, as long as we ask the expert to identify it, they will tell you the approximate time of writing on the preparation note, which is obviously the preparation note you have used in the past. You don't think that we are not bluffed by you, that we are not deceived by illusions, and that we see the essence through phenomena - that's what we do; You just mentioned books, so I will talk about books, which are the textbooks you use in your studies at the teachers' college, and have nothing to do with the content of your current teaching. ”

"Yes, these books are indeed the books I read when I was in college, who stipulates that after graduation and going to work, you can no longer read the books you have read before, which can only show that you know very little about the things of the school, now, all kinds of educational ideas, all kinds of educational concepts collide with each other, and the means and methods of teaching are constantly improving and innovating, but no matter how to improve and innovate, there must be a certain level of knowledge and theory to support." When it comes to education and teaching, Li Dongting does have the right to speak, "Since you have already put this thing on my hand, you must already have conclusive evidence, and I hope you will come up with evidence." You're always dwelling on inconsequential details - I'm confused by you. ”

"You know it - it's not confused at all, but your parents and family are in the dark, okay, then I'll talk about it, two old people, at five o'clock in the afternoon on the twelfth of this month, there was a tragedy at No. 206, Building 5, Duolun Road Street, Xiaguan District, the murderer killed Teacher Liu and her two granddaughters in more than half an hour, in addition, Teacher Liu's black handbag containing 260,000 yuan was also missing. By now, you should understand what's going on! It's been in the newspapers, it's been reported on TV -- I'm sure you're already aware of it. Now, the families of the deceased are in tears all day long. No one can withstand such a blow. ”

Mr. Li glanced at Li Dongting, who was sitting on the side, and this time, there was despair and helplessness in his eyes.

"Comrade policeman, do you suspect that my brother has something to do with this case?" Li Dongmei said.

"The black handbag that Mr. Liu's house didn't see is similar to this black handbag, but we can be sure that this is not the bag that Li Dongting brought back tonight, nor is it the handbag that disappeared from the scene of the crime."

"Comrade policeman, this is a matter of human life, and if there is no evidence, you can't arrest people casually." The old lady was encouraged by her son and daughter, and she was more confident to speak.
