Second, to let Che Huating provide all the tenant's information, in addition to Che Huating, but also to talk to Che Huating's wife, after four or five years, Che Huating may have some omissions, so the information provided by Che Huating's wife will be an important supplement - this should be an indispensable part. In addition to Che Huating and his wife, they also have to go to the neighbors to investigate, in the south and north lanes, there are many shops, there are also many households, and there is a courtyard on the south side of No. 157, there are three families living in the yard (these situations are provided by Director Gu), this part of the people can not be ignored.

Thirdly, if the deceased was not a local, then he must have been one of the tenants, and among the many tenants, was there anyone between the ages of fifty-six and fifty-eight? Director Gu prefers that the deceased is a tenant, and his basis is that, first, the house is on the Che family, and no one in the Che family is missing except for Che Rengui, who ran away from home in May 1990; Second, he had been the head of the Zhonghe Street Police Station for many years, and he had been working here before he became the director, and he was very familiar with the area, and if anyone was missing, he would definitely know about it.

Director Gu also mentioned a very important situation: there is a tea stove, a fried goods shop, and a grocery store at the mouth of the south lane. All the residents and tenants living in this area will go to the tea stove to boil water, and they will go to the roast shop to buy snacks such as melon seeds and peanuts, and the tea stove is guarded by an old lady surnamed Li; The grocery store deals in pots and pans, and all tenants who live in this area will go to the grocery store to buy daily necessities when they first move in; At the mouth of the north lane, there is a pickle shop, a bathhouse, where female tenants will go to the pickle shop to buy side dishes, and men will go to the bathhouse to take a bath; At the entrance of the bathhouse there was also a shoe repair stall, and the master shoemaker was surnamed Jiang, nicknamed Jiang Crooked - his head was a little crooked. Jiang Crooked Zi has a very good memory, he has to repair a lot of shoes every day, whether it is an old customer or a new customer, he will never make a mistake.

Soon after the comrades returned to No. 157, Che Huating came by appointment, and he had just sent the workers to the bathhouse to take a bath, and each of them paid twenty yuan in wages. No. 157 is back in Che Huating's hands, and the house is definitely going to be rebuilt - but not until the case is cleared.

When Che Huating walked into the living room, Yan Jianhua, Zuo Xiangdong and Director Gu walked out of the small door. They were going to Che Huating's house to find Che Huating's wife to understand the situation.

The conversation took place in the south wing on the west side of the aisle.

The conversation revolves around the house and the tenants.

"When was this door on the north side of the aisle sealed?"

"It was sealed in 1986."

"When did you start renting it to someone else?"

"1980 - rented to someone else before it was assigned to me."

"When was it given to you?"

"In 1987, we lived here for a while, and then we rented it to someone else."

"Why rent it to someone else?"

"Since the two children moved in, they have often had nightmares when they sleep at night, so my mother asked us to rent out the house."

"Does your mother know anything?"

"Yes, under our questioning, she said."

"What did she say?"

"She said two people had been hanged here -- but that was many years ago."

"Could you please seriously recall that since 1989 and 1991, which tenants have lived here?"
