So, will Master Kong not ask anything here?

After talking, Ouyang Ping learned that Master Kong turned out to be a very responsible doorman, Lin Haiquan also confirmed this, as long as he found a suspicious person, Master Kong would come forward to interrogate, usually, he would take a red armband to the community to go around a few times. Because of Master Kong, there has basically been no accident in their community.

While chatting, Master Kong was talking to Ouyang Ping, while looking out of the door and window, almost everyone who entered and exited the community had to bow down under Master Kong's eyelids.

"Master Kong, how many years have you been watching the gate here?"

"From 1975 to now, it's been 20 years."

"You must be very familiar with the people in the community."

"Except for the newborn doll, there is nothing I don't recognize. Whether it's someone in this neighborhood or not, I can recognize it at a glance. ”

"Between 4:20 and 5 p.m. on the 12th, did you see a person wearing a yellow raincoat entering and leaving the community?"

"On the afternoon of the twelfth day, it was the afternoon of the accident at Mr. Ma's house, and that afternoon, it rained very heavily and for a long time, between four and five o'clock, the rain was very heavy."

"Master Kong, you have a really good memory." Ouyang Ping hoped that Master Kong could come up with something.

"Between 4:20 and 5 p.m. on the 12th, no one wore a raincoat to enter or leave my gate."

"Are you so sure?"

"There will be no mistake, between four and five o'clock, the people who enter and exit my gate are not students who are out of school, or people who go to the vegetable market to buy vegetables, students will not wear raincoats, people who buy vegetables will not wear raincoats, and those who wear raincoats will only be those who commute to and from work, and before half past five o'clock when they get off work, if they wear raincoats, they will definitely have to ride bicycles, walk and take buses to and from work, and they will definitely not wear raincoats."

What Master Kong said is very reasonable. He's not a dry eater - he's not an ornament.

In this way, there are two possibilities; The first possibility is that the murderer is a person from the community, and if the murderer is a person from the community, he does not need to enter or exit the gate of the community. The murderer wore a raincoat, and in addition to keeping out the rain, the main purpose was to cover his face; The second possibility is that the murderer is not from the community, and Master Kong did not see the person in the raincoat entering and exiting his door, which does not mean that the person in the raincoat did not enter and exit through the small door of the vegetable market.

"Master Kong, do you know the master who decorates in the community?"

"I know, if they want to decorate the community, they must first register with me. I'll show you something-" Master Kong took out a notebook from the drawer of the desk and opened it to one of the pages, "Look-"

The names of two people were written on the notebook: Huang Gongqin and Min Dongshui. There is also an ID number, the registration time is May 17, 1995, and the house decorated is No. 305, Building 3.

Ouyang Ping had to be in awe of Master Kong. People who have come in the past have been thoughtful and meticulous in doing things.

"They enter the community at 7:20 in the morning and leave the community at 8:30 every night." Master Kong said, "They have been working in this community for more than half a year, by the way, they have also done decoration in Mr. Ma's house." ”

"On the night of the twelfth, when did they leave the community?"
