Let's take a look at the first one, the tenants between July 1989 and June 1991.

During this period, there were a total of 11 tenants, the longest staying for four months, the shortest staying for just over a month, and one tenant rented it twice. This person's surname is Ma and he has no name. Each stay lasted about two months. The two rentals were August-September 1989 and April-May 1991 - and this is only an approximate time.

"Che Huating, is this surnamed Ma the same person?"

"Yes, a person. The surname Ma is a foreigner, and every time he comes to live, he doesn't stay for a long time. ”

"What does he do?"

"I didn't ask, and the couple didn't say, it looks like they're coming to Jingnan for fun -- or to do business. As for what kind of business they do, I don't know, they seem to be very leisurely every day, there is no regularity in their work and rest, and they are also very particular about people, not only dressing well, but also eating and living - women love to be clean. ”

"Is it just a husband and wife?"

"Just husband and wife. By the way, the surname Ma doesn't speak much, but he speaks in a crepe, and he knows that he is a literate person when he hears it. His wife was very beautiful and fashionably dressed - at first glance she knew that she was a rich wife. By the way, they were the only ones who signed a lease agreement with me, stayed twice, and they signed twice. I said no, but he said it had to be this way - everything was done according to the rules. ”

"Is the lease agreement still there?"

"I didn't take it seriously, and after signing the agreement, I didn't know where to put it? Maybe it's still there, but if you need it, I'll go back and look for it. But don't expect me to find it, I'm not particular about what I do, and I haven't seen that piece of paper again. ”

Che Huating said a lot about this surnamed Ma, but Ouyang Ping and Liu Dayu were not very interested, first, the time when this person rented No. 157 and the time when the deceased was killed were either in the front or behind, especially the time when this person rented No. 157 for the second time, which was even more backward: Second, a person who rented No. 157 twice could not be the murderer of the deceased. Whether it is from a rational point of view or a logical analysis, after killing someone, you should avoid it. Third, the rooms rented by Ma twice before and after were not the same room, and the possibility of committing the crime was even less (the first time, Ma lived in two east wings, and the second time, Ma lived in two west wings. ）

In addition to the surname Ma, the situation of the other nine people is as follows (the author truthfully transcribed the content written on the note by Che Huating, and in order to ensure consistency, the author also transcribed the situation of the tenant surnamed Ma below):
