Qin Huaiyu nodded, with a hint of fear in her eyes: "Yes, mother. I always feel that he is still nearby, maybe he knows some of our secrets."

Sheng Yunrong's expression became serious. She held her daughter's hand tightly and said, "Yu'er, you must tell me the truth. Who is that person? Why did he appear in the Qin Mansion?"

Qin Huaiyu took a breath and tried to calm herself down. She said slowly, "Mother, that man's name is Zhao Xuan. He was once a guard in the Qin Mansion. He was expelled from the Qin Mansion for making a mistake, but he has always held a grudge. He came back this time, and he must want to take revenge on us."

Sheng Yunrong's expression became more and more solemn. She was silent for a moment, then slowly spoke: "Yu'er, you know that the power of the Qin Mansion is not something he can shake. But this matter cannot be ignored, you must be careful."

Qin Huaiyu nodded, a hint of determination flashed in his eyes: "Don't worry, mother, I won't let him hurt us. It's just... I'm worried that he will find a chance to harm the Qin family."

Sheng Yunrong sighed and patted her daughter's shoulder gently: "Yu'er, you are a smart child. I know you have been working hard to protect the Qin Mansion, but you must also learn to protect yourself."

At this point, Sheng Yunrong's expression softened, and she gently stroked her daughter's cheek: "Look, you've lost a lot of weight recently. You always worry about the Qin family, but ignore your own body."

Qin Huaiyu's eyes moistened, and she hugged her mother tightly: "Mom, I know you are worried about me. But I am the daughter of the Qin family, and I have the responsibility to protect the safety of the Qin family."

Sheng Yunrong felt a warm current in her heart, and she hugged her daughter tightly: "Yu'er, you are a brave child. But you must also understand that your safety is equally important to us."

The two of them sat hugging each other, the atmosphere was warm and heavy. Sheng Yunrong suddenly remembered something, she gently pushed Qin Huaiyu away, her eyes flashing with wisdom: "Yu'er, do you remember the woman named Lin Shiyin?"

Qin Huaiyu was slightly stunned, then nodded: "Remember, she was a maid in the Qin Mansion and was expelled from the Qin Mansion for stealing."

Sheng Yunrong smiled slightly: "Yes, that Lin Shiyin. She was once a maid in the Qin Mansion, but was expelled because of an unjust case. Later, she met Zhao Xuan, and the two joined forces to take revenge on the Qin Mansion. But in the end, they failed."

A trace of doubt flashed across Qin Huaiyu's eyes: "Mother, you mean..."

Sheng Yunrong nodded: "Yes, Yu'er. The examples of Lin Shiyin and Zhao Xuan tell us that the power of the Qin Mansion is not something they can shake. You just need to do your best and protect your own safety, and leave the rest to the Qin Mansion."

Qin Huaiyu's eyes flashed with determination, and she held her mother's hand tightly: "Mother, I understand. I will protect myself and the Qin Mansion."

Sheng Yunrong smiled slightly and patted her daughter's hand gently: "Good girl, I believe you."

Qin Huaiyu smiled and said, "Of course, it is to let mother continue to teach me daily etiquette and teach me what I have learned in the past."

Sheng Yunrong heard this, a hint of approval flashed in her eyes, but she still kept a faint smile on her lips. She patted Qin Huaiyu's hand gently and said softly: "Yu'er, you are such a smart child. However, what your mother taught you is not only daily etiquette, but also the wisdom of dealing with people."

Qin Huaiyu lowered his head slightly, with a curious light in his eyes: "Mom, what are you going to teach me today?"

Sheng Yunrong pondered for a moment and said slowly: "Today, I will teach you how to recognize people's hearts and distinguish between good and evil. People in this world are treacherous. If you can understand the mystery, you will be able to navigate this deep mansion with ease."

Qin Huaiyu's eyes flashed with determination, which was the deepest love her mother had for her. She nodded slightly, indicating that she understood.

Sheng Yunrong watched her daughter grow up, feeling very happy. She picked up the teacup on the table and said softly, "The human heart is like tea. It looks calm on the surface, but it is actually turbulent. Yu'er, look at this cup of tea. It looks calm on the surface, but the tea leaves are actually surging in the water."

Qin Huaiyu followed her mother's gaze and found that the tea leaves in the tea were shaking slightly. She nodded thoughtfully.

Sheng Yunrong continued, "This tea is like the people in this world. Some people appear kind on the surface, but are actually scheming; some people appear indifferent, but are passionate inside. You have to learn to observe and feel with your heart."

Qin Huaiyu frowned slightly, seeming a little confused: "Mom, how should I observe and feel it then?"

Sheng Yunrong smiled, her eyes full of love: "Yu'er, you have to remember that observing a person's eyes is the most important thing. The eyes are the windows to the soul, and both good and evil are in them. Also, when talking to people, pay attention to their words and actions, and see if there are any contradictions."

Qin Huaiyu listened carefully. These were her mother's life experiences over the years. She tried to understand and comprehend them.

At this time, a maid came in with a plate of fresh fruit in her hands. Sheng Yunrong motioned for her to put it down and continued to talk with Qin Huaiyu.

"Yu'er, do you know? There are many people in the Qin Mansion who want to take advantage of the opportunity to get close to us, and there are also many people who want to frame us. You have to learn to distinguish who is truly kind to you and who has other intentions."

Qin Huaiyu's eyes flashed with determination: "Mom, I will remember it. I will use my heart to feel everyone and not let those sinister people take advantage of me."

Sheng Yunrong gently patted her daughter's shoulder, her eyes full of relief: "Yu'er, mother believes in you. You are a smart child. As long as you work hard, you will definitely be able to gain a foothold in this Qin Mansion."

The warm sun shines through the window lattice, onto the exquisite nanmu wood floor, reflecting the warmth of the room. Sheng Yunrong looked at her daughter Qin Huaiyu, her eyes full of satisfaction. She smiled and said, "Yu'er, you are getting better and better at dealing with things. Mother is very happy."

Qin Huaiyu smiled slightly, her eyes revealing her admiration for her mother: "Mom, it is because of your good teaching that my daughter has made such progress today."

Sheng Yunrong gently patted Qin Huaiyu's hand and said, "Okay, Yu'er, I know you have many questions in your mind, so I'll let you ask enough today."

Qin Huaiyu's eyes flashed with joy. She knew that her mother was encouraging her to raise her doubts. She lowered her head slightly, thought for a moment, then looked up at Sheng Yunrong and said, "Mother, why do people in the mansion respect you so much?"

Sheng Yunrong smiled slightly, with a look of indifference in her eyes: "This is because I always stick to the right path, treat everyone in the mansion fairly and justly, and let them feel the warmth of home."

Qin Huaiyu nodded thoughtfully, and then asked, "How does mother view her daughter's future?"

Sheng Yunrong's eyes were filled with more kindness, and she whispered, "Yu'er, your future is your own. I only hope that you can become a woman of virtue and talent, and be able to face the challenges of life independently."

At this time, there was a sound of footsteps outside. It turned out that the housekeeper of Qin's house came to report some household affairs. Sheng Yunrong frowned slightly and said to the housekeeper, "I know, you go and handle it."

The housekeeper agreed and left. Sheng Yunrong turned around and looked at Qin Huaiyu and said, "Yu'er, do you know? As the master of the mansion, we have to learn how to handle these tedious affairs."
