Half past six in the evening.People who have worked all day have finished their work and it is time for them to go home.Outside the entrance of an alley near Liudaokou, the Crown sedan shut down and stopped, almost blending into the night.Da da da……The cowhide soles of his shoes knocked against the bluestone slabs in the alley.Counting the house numbers, Li Jiankun stood in front of the gate of a large courtyard.The courtyard door is not closed.Through the gate, you can see that it is very lively inside. Two families have set up small tables outside the door and the whole family is having dinner.The men were still talking to each other, and they raised their glasses and drank from a distance."Excuse me, does Comrade Yang Xingmin live here?"Hearing the sound, everyone in the yard turned their heads and looked over.When the young girls and wives saw that he was a tall young man wearing a long windbreaker and had an extraordinary demeanor, especially when they saw that he was holding gift boxes of Maotai liquor and Longjing tea in his hands, they were obviously a little embarrassed.The rough movements were restrained, and eating became chewing slowly.Next to a small table, a middle-aged man still wearing postal green pants stood up in astonishment and said word by word:"You're looking for me?"After Li Jiankun saw his pants clearly, he knew he had found the right person. He nodded, walked through the gate and went in.The wife of the Yang family hurriedly made way for the small dining table, winked at her son and daughter-in-law, asking them to keep an eye on the two naughty kids, and then asked Li Jiankun with a smile:"Have you eaten? The food at home is not good, but we still have some rice. How about a quick bite?"Li Jiankun expressed his gratitude with a smile and said that he had eaten it.Yang Xingmin glanced at the two bottles of Moutai and the even rarer Longjing tea gift box placed on the ground beside his legs, and felt inexplicably nervous.He thought, he was just a district postman.But I don't have any great abilities.What a big deal to help others do."Who are you?" he asked.Li Jiankun smiled and said, "I am from around here too. I want to ask you something."As Li Jiankun spoke, he took out the white envelope from the lining of his beige windbreaker and handed it over with both hands:"Did you deliver it to this address?"Yang Xingmin took it and looked at it, then said without hesitation, "Yes, I have a deep impression of this family. The father is disabled but determined. He runs a stall at the entrance of their alley to repair shoes. In fact, the family lives a good life. The daughter is a college student cadre, works in a newspaper, and has a private car."He still didn't understand the purpose of this precious young man looking for him.Anyway, he should tell you what he knows first."Then do you know where this letter was sent from?" Li Jiankun asked again."Huh? This?"Yang Xingmin spread his hands, helplessly saying, "I don't know. It's an anonymous letter, and there's no return address on it."Li Jiankun then asked: "Where did you get the letter from?""The post office."Yang Xingmin explained: "There are many people in the bureau, with different divisions of labor. Someone is responsible for sorting out the letters for each area. I pick them up when I go to work in the morning and start delivering them."Li Jiankun didn't know much about the work of the post office, although he could imagine that it was like that."Does your post office have any records that can track where each letter was sent from and where it was sent to?""This... I don't know, but I don't think so. How much work would that be?"A hint of sadness appeared in Li Jiankun's eyes.In an era when information was not well developed, it was really not easy to trace the origin of a letter.Unlike later times, when letters are sent to every station via mobile phone, they can be checked in real time."Okay, thank you."Li Jiankun stood up from the small bench, said goodbye and left.Yang Xingmin pointed at the Maotai and Longjing tea gift boxes on the ground: "Hey, these things——""Excuse me for bothering you, just a small token of my appreciation."Li Jiankun turned and walked out the door. When Yang Xingmin wanted to say something else, the wife put down the bowl and covered his mouth with her hand."No, no, I want to talk about something serious."Yang Xingmin pried open the woman's hands and shouted, "Hey, young man, let me remind you that if you investigate anonymous letters, you might get into trouble."Li Jiankun turned his head and smiled at him, indicating that he understood.When Li Jiankun disappeared outside the courtyard gate, the neighboring family was envious. The male host held up the empty wine glass and pretended to ask for more:"Xingmin, it's Maotai, why don't you give me a glass?"Without waiting for Yang Xingmin to reply, Yang's wife happily picked up two bottles of Maotai and a gift box of Longjing tea and walked into the house: "You are so beautiful.""Ha ha!"The neighbors were just joking. Even if they had some at home, for a family like theirs, who would open the wine and drink it unless it was New Year's Eve?It is said that the Yang family also had a visit from the God of Wealth today. They just casually said a few words and did not even help others, but received such a valuable gift.…………"Director Chen, someone wants to see you.""I'm busy now. I have a meeting soon.""You might have to meet him.""Oh? Who is it?""General Manager of SEZ Huadian Company, Li Jiankun.""Him? Come in, come in."Li Jiankun thought about it and decided that since it was so difficult to track down an anonymous letter, he should look for the person with the greatest authority.If this person has no way.It just means that this road is indeed not feasible.It must be said that he may be the largest customer of Post and Telecommunications.Not long after, under the guidance of the secretary, Li Jiankun met Director Chen.Some polite greetings are inevitable.Five minutes later, we got to the point.After learning his purpose, Director Chen's smile gradually faded and he said:"Manager Li, do you know why anonymous letters are called anonymous letters?"Since this kind of letter is allowed to exist, tracking it... is unacceptable."Li Jiankun asked without changing his expression: "Can it be tracked?"Director Chen smiled bitterly: "You came to the Post and Telecommunications Bureau and asked me if I could track down the anonymous letter... You are trying to make me make a mistake.""A human life is involved here, that of a sixth-grade student."As Li Jiankun spoke, he took out the white envelope, pulled out the red-lined letter paper inside, and handed it over.After taking it and examining it, Director Chen pondered and said, "Even so, you should call the police first. Only if the police intervene can we help."Li Jiankun's eyes lit up: "So it can be tracked?"Director Chen stretched out his hand and said, "Let me see the envelope."Li Jiankun did as he was told.After taking a look at the envelope, Director Chen said, "This letter was sent from the capital.“Tsk, it’s not a letter from the unit.“It can only be traced to one area.”"That's fine!" Li Jiankun was delighted.Director Chen looked at him.He also looked at Director Chen."So I have to go to the institute now so that you can say what you want to say." The smile on Li Jiankun's face disappeared and he stood up from the red lacquered wooden sofa.After hesitating for a moment, Director Chen stood up, put on a smiling face, and helped him sit back in his seat:"Hey, I'm just saying that normally it would be like this, but in an emergency, this involves a child's life, what if we miss the rescue time, right?"Please sit down first. I will arrange a car to take you there right away.""I have a car." Li Jiankun said."Then I'll arrange for someone to take you there."Li Jiankun asked: "Where are you going?""It's where I send letters."Director Chen picked up the white envelope from the red lacquered wooden coffee table, poked the blue stamp on the stamp with his finger, and said, "There is information on it that most people don't know."But you have to be mentally prepared. It's difficult to locate the sender of the letter in that place!"An hour later, Li Jiankun returned to Haidian.Standing at the gate of the Summer Palace.Outside the red building's gate with flying eaves and pointed corners, there is a green mailbox in the shape of a flower basket on the left side of the stone steps.The person arranged by Director Chen said that the letter was delivered to this mailbox.Looking at the tourists coming and going at the gate of the Red Building, Li Jiankun's eyes went dark.…………Li Jiankun walked along the secret passage and bumped his head against the south wall.However, the hunt for Xu Qing has lasted for so long, and this letter is the only clue.In the following days, Li Jiankun seemed to be possessed by a demon.The cat stayed in the courtyard, never going out of the front door or the back door, holding the letter in his hand, sometimes turning it over and over, sometimes staring blankly.Mrs. Yuying saw it all and was worried.She knew that as an old woman with no education, she could not comfort her son, so she had no choice but to call her godson to come over.Wang Shanhe came with Luna and brought Wang Chaodi with him.Seeing his godson, Li Jiankun finally let go of the letter, picked up the baby and teased him, and a smile appeared on his much thinner face."I want to see this letter. Is that okay with you?" Wang Shanhe said, pointing to the white envelope on the five-drawer table.As the saying goes, no matter how many times Jiankun abuses me, I will still treat him like my first love.He had an important event today, which was about the establishment of the first auction house in the capital. After receiving a call from his godmother, he hurried over here in a hurry. On the way, he thought that they had just had a big fight and he probably couldn't do anything, so he drove to pick up his son.After all, he has a lot of face.Li Jiankun was busy teasing his godson and ignored him.Wang Shanhe picked up the letter and pulled out the red-lined paper to read it.Luna tilted her head to take a look, wanting to see what was written in the letter that caused the cancellation of Kun Ge and Hong Yi's wedding and made Kun Ge crazy."Eh?"Wang Shanhe was furious. He turned his head to look at his wife and asked, "What's wrong?""I think I've seen this handwriting before."Swish!In almost 0.5 seconds, Li Jiankun rushed to the two of them and stuffed his godson back into his father's arms. Then he held Luna's shoulders and asked with wide eyes:"Xiao Na, do you recognize this handwriting?""It seems... I've seen it somewhere.""where?""I can't remember it at the moment.""..."Li Jiankun helped her sit down on the sandalwood official hat chair next to the five-drawer table: "Come, come, sit here and think carefully."Shanhe, take Didi out and don't disturb her."When Wang Shanhe left, he looked at his wife in surprise and asked, "You still have this ability to remember everything you see?"Luna was already lost in her memories. She knew that this was very important to Brother Kun. She searched carefully in her mind and replied casually, "It should be something quite important. I have seen it before."Hearing this, Li Jiankun was overjoyed: "Think about it carefully, think about it carefully."He also left the room and closed the door, but did not go far. He guarded the door to prevent anyone from entering and disturbing Luna."right!"Just five minutes later, a sound was heard from the bedroom.Bang!Li Jiankun broke open the door.Luna turned her head and looked at him, saying: "Brother Kun, do you still remember that year when you asked me to take over a shop in the Zan'an Courtyard, and you said that all the money earned would belong to me.“That was the first time in my life that I had my own business.”Li Jiankun nodded and said, "It is Qingjiangfang that will be taken over, and you will sell tapes later."Luna nodded slightly and continued:"At that time, all the shop owners in the courtyard had to write an agreement and a letter of guarantee. I didn't know how to write it. I forgot whether it was written by Jin Biao or Chen Yajun. He threw the letter written by the previous shop owner to me and said it would be invalid anyway. He asked me to change my name and copy it. I had to tear it up after copying it."This handwriting is the handwriting on it."Lu Na and Li Jiankun looked at each other and said in unison: "Liu Xiaojiang!"
