Ma Mingyang was carrying a black handbag in his hand.

The lock on the door of Jiang Feng's house is a "Yonggu" brand iron lock.

Ma Mingyang opened the handbag, took out an iron box from inside, opened the iron box, and took out a crochet-like steel wire from inside.

Ma Mingyang put the front end of the wire into the keyhole, only shook the wire a few times, and with a "click", the lock opened.

Ouyang Ping pushed open the door, and sure enough, there was no sound.

Liu Dayu and Yan Jianhua squatted down and checked the door nest, there was nothing in the door nest, and then looked closely, a piece of cloth was wrapped on the door shaft.

Everyone finally understood that when the door shaft and the door socket rub against each other, it will definitely make a sound, but if you wrap a piece of cloth around the door shaft, the sound will be broken down a lot.

The person who understands the most should be Han Lingling, the reason why Jiang Fengqi wrapped a piece of cloth on the door shaft is that he doesn't want his neighbors to hear the sound of opening and closing the door, so that when it is more quiet, the woman can enter his room silently, and of course, Jiang Fengqi can also enter and exit his room silently. No wonder Xie Yao's wife and daughter didn't hear the sound of Jiang Feng opening and closing the door in the early morning of January 28. There should be a sound when the door shaft rotates inside the door socket, and the sound will be clearer when it is more quiet. Jiang Fengqi is honest on the surface, but secretly he is doing despicable things.

The furniture in the room is very simple, there is a bed in the inner and outer rooms, and there is no cover on the bed in the outer room, Chen Guoquan's mother-in-law said: "The bed outside is for the children, and the children have to come back once or twice a year. The bed outside was given to Jiang Fengqi when Chen Guoquan's family changed furniture, Jiang Fengqi was alone, the child was not around, Chen Guoquan was very sympathetic to his experience, when Jiang Fengqi came back from northern Jiangsu, in addition to a bag, it was a bedding. Therefore, the dilapidated furniture and daily necessities that Chen Guoquan's house bought and replaced were all given to Jiang Fengqi.

There was a large table outside, there were three obvious gaps on the tabletop, one leg of the table was shorter, Jiang Fengqi added a piece of wood under this table leg, and two wooden boards fixed the table leg and the wood together, and several iron nails were nailed into the board. There was also a chair, two benches, and a cupboard with tattered yarn. Several wooden strips were nailed to the chairs and benches.

Next to the cupboard, near the door, there was a coal stove, and beside the coal stove lay dozens of coal bases, on which lay a square rattan basket with tongs, stove hooks, firewood, corn and pine fruits. Next to the coal base is a small square bench, on which is a kerosene stove. The old man said that Jiang Fengqi used a kerosene stove for cooking most of the time, and the coal-based stove was basically not used.

In addition to a bed, there is also a half-section cupboard, a hanger, three wooden boxes, and a basin rack.

Although the home is very simple, it is very clean and does not look messy at all.

Jiang Feng Qi is a very organized person, and things that are often used like hammers are not thrown around. What's more, the inside of the house is so simple, and the simplicity can be described as "four walls".

By the way, there are two stacks of newspapers on the windowsill in the outer room.
