The Courtyard House: The story begins with He Yuzhu beating up the White Widow.

Yan Bugui said anxiously, "Ruihua, this is terrible! That brat He Yuzhu has become a policeman. And he knows about the rumors about him that are circulating about our family. He just told me in front of me that he's going to investigate the person who spread the rumors and that he's going to make that person keep Jia Zhangshi company."

"What?!" Yang Ruihua was also startled. He asked, "Old Yan, what should we do now?! What if he finds out we spread rumors about him?! Our family will be finished! What should we do?!"

"What do we do?! You're asking me?! Who am I supposed to ask?!" Yan Bugui was getting anxious. They say the common people can't fight with officials, and Yan Bugui originally thought He Yuzhu was just a purchasing agent in the military control commission, nothing serious! Even if some rumors spread about him, it would only damage He Yuzhu's reputation. But now He Yuzhu is a policeman. This is troublesome.

At this moment, Yan Bugui's mind was racing, like a computer at high speed, weighing the pros and cons. After a long while, Yan Bugui, in a moment of inspiration, said, "Neither of us can admit to this. If I do, I'll likely be expelled from school. If you do, our family's reputation will be completely ruined. The only way now is for Jie Cheng or Jie Fang to admit to it. If Jie Fang admits it, at most he'll get a reprimand, and nothing else will happen."

Yang Ruihua asked, "Will the Liberation Army admit to this?!"

Yan Bugui showed no sign of his previous panic, appearing confident and composed. He said, "Getting Jiefang to admit fault is easy! I'll talk to him later, and I guarantee we can settle this. When He Yuzhu returns tonight, have Jiefang go to his house to apologize. Out of consideration for being neighbors, He Yuzhu won't make things difficult for Jiefang."

Hearing Yan Bugui say this, Yang Ruihua finally felt relieved.

He Yuzhu arrived at the police station and reported to the logistics section. Then he went to buy groceries. A little after 8:30 a.m., He Yuzhu returned with the groceries, changed into civilian clothes, and left the police station on his bicycle.

It's likely that He Yuzhu didn't consult the almanac before leaving home today, or perhaps he was just incredibly lucky, striking it rich as soon as he stepped out the door. He Yuzhu had just turned into Baochao Hutong on his bicycle when his divine sense swept over an old man and a middle-aged man emerging from a courtyard house. He discovered that both of them were enemy agents. The old man was a double agent for both the Japanese and the bald man. Judging from their names, the old man and the middle-aged man were probably father and son. He Yuzhu's divine sense quickly enveloped the courtyard house from which the father and son had emerged. Soon, He Yuzhu discovered a secret room beneath the main building in the west wing. Inside the secret room were piles of more than a dozen boxes and wooden barrels.

"Young man, who are you looking for?!" Just as He Yuzhu was in a daze, an older woman appeared beside him. She looked He Yuzhu up and down with a suspicious gaze and asked.

He Yuzhu asked, "Auntie, do you know those two people who just passed by?!"

The older woman asked, "Why are you asking this?!"

He Yuzhu replied, "The older one looks a lot like one of our relatives. So I'm asking to see if he's a relative."

The older woman asked, "Comrade, where do you work?"

He Yuzhu's eyes darted around, and he blurted out, "I work at the Military Control Commission."

"Zhu Zi, what are you doing here?!" Just then, Zhang Lan and Xu Qinyue from the Military Control Commission walked over.

He Yuzhu greeted them, "Sister Zhang, Sister Xu, another mission from above?!"

Zhang Lan said, "The military control commission is about to be changed into a subdistrict office. We are making preparations for the handover."

The older woman asked, "Comrade Zhang, Comrade Xu, is this man from your military control commission?!"

Xu Qinyue replied, "Aunt Gu, he's one of ours."

Hearing Xu Qinyue's words, the older woman immediately felt relieved and said, "Comrade, the two people you just asked about live in the main house of the west wing of our compound. There are six people in their family: an elderly couple and two young couples. The older one is the father, Gao Xiongyi, who works at the Sijiucheng Machine Tool Factory. The other one is his eldest son, Gao Songming, who works at the Shijingshan Power Plant. The younger son is Gao Songgang, who works at the rubber factory outside Dongzhimen. The three women in the family all work at the Sijiucheng No. 2 Girls' Middle School near Dongzhimen."

Zhang Lan asked, "Zhu Zi, is there something wrong with that family?!"

He Yuzhu asked, "Aunt Gu, when did they move in?!"

Aunt Gu replied, "Our family moved here right after Liberation. This family was already here when we moved in. We're definitely local residents."

"Thank you!" He Yuzhu greeted Aunt Gu, then looked at Zhang Lan and Xu Qinyue and said, "Sister Zhang, Sister Xu, if there's nothing else, I'll be going now!" With that, He Yuzhu rode away on his bicycle.

After He Yuzhu walked away, Zhang Lan said, "Aunt Gu, you must not tell anyone about the questions I just asked you."

Aunt Gu said, "Comrade Zhang, don't worry! I know what I'm doing!"

He Yuzhu "strolled" through two alleys and, seeing that it was almost time, rode his bicycle back to the police station. Just as he parked his bike in the shed, Instructor Ye Guoliang appeared behind him, smiling and asking, "Zhuzi, where did you go this morning?!"

He Yuzhu said, "Instructor Ye, the director gave me a task. Every day after purchasing ingredients, I have to ride my bicycle around our jurisdiction. And believe it or not, I actually made some gains today."

Ye Guoliang understood what He Yuzhu meant by "gains," and immediately perked up, pulling He Yuzhu towards Zhang Qiang's office. He Yuzhu struggled, saying, "Instructor Ye, don't pull me! Let go! It won't be good if others can't see us! I can walk by myself!"

Ye Guoliang immediately released He Yuzhu's hand, apologetic, and said, "I almost forgot! You work at our institute now."

He Yuzhu sighed and said, "Instructor Ye, even if I don't work at our station, you can't do this! I haven't done anything wrong! If people misunderstand, I won't be able to explain myself even if I have a mouth all over my body."

"Hey kid!" Ye Guoliang pointed at He Yuzhu twice and urged, "What are you still standing there for?! Hurry up and go!"

"Oh!" He Yuzhu responded, following Ye Guoliang toward the director's office like a dutiful daughter-in-law.

"Hey?! What brings you two here?! Come in quickly!" Ye Guoliang and He Yuzhu had just arrived at Zhang Qiang's office door when Zhang Qiang finished his work and was about to go to the cafeteria for lunch. Seeing Ye Guoliang and He Yuzhu at the office door, he smiled and invited them in.

Ye Guoliang led He Yuzhu into the office and said, "Old Zhang, this kid gave us a great start today."

"What do you mean?!" Zhang Qiang unconsciously looked at He Yuzhu.
