Upon hearing this, Lin Jin smiled warmly and replied, "Aunt Yu, I'm from Pingji County in Suzhou. I wonder which part of Suzhou you were sent to work in the countryside back then?"

Yu Zhenzhen said excitedly, her voice trembling slightly, "I was sent to the countryside in Songqing Brigade, Pingji County! I wonder if Dr. Lin knows anything about this place!"

Lin Jin smiled and nodded, replying softly, "Yes! Of course I know, I used to go there with my grandma to exchange for tofu when I was little!"

Yu Zhenzhen looked surprised and asked curiously, "Since you're from the countryside, why did you go to work in the countryside?"

Lin Jin's smile faded slightly, a hint of sarcasm flashing in her eyes, as she slowly said, "Actually, my household registration is in the city, and my adoptive parents are both workers. However, they were too busy with work to take care of me, so they sent me to my grandmother's house in the countryside. I lived with my grandmother until she passed away, and only then did I return to the city. But my adoptive sister didn't want to go to the countryside, so my adoptive parents ultimately decided to register my name so that I could go to the countryside in her place."

Yu Zhenzhen gazed at Lin Jin with a face full of tenderness and asked softly, "What about your biological parents? Have you seen them? Do you know their whereabouts?"

Lin Jin slowly shook her head, replying with an even more sarcastic tone, "I don't know where they are, and I don't want to know at all."

As soon as he finished speaking, Lin Jin's emotions seemed to fluctuate. His voice lowered slightly, revealing a hint of displeasure.

Yu Zhenzhen keenly noticed the change in Lin Jin's tone, and she quickly explained, "Oh dear, Dr. Lin, I'm so sorry, I just asked out of curiosity, I didn't mean anything by it, I don't know anything about you..."

However, Lin Jin realized that he was losing control of his emotions, so he quickly interrupted Yu Zhenzhen and said, "Aunt Yu, don't take it to heart. I just suddenly feel a little sad. It has nothing to do with you." Seeing that Lin Jin's emotions had calmed down, Yu Zhenzhen hesitated for a moment and then asked, "Dr. Lin, where did your parents find you?"

Lin Jin shook her head and said, "I don't know. Maybe they stole it! Or maybe they switched me with their own child."

As Lin Jin finished speaking, his eyes were fixed on Yu Zhenzhen! Yu Zhenzhen looked at Lin Jin in disbelief and said, "Steal? Why? Don't they have children of their own? Why would they steal them and then not raise them? What are they after?"

Then he added, "You just said they switched them! Switched your own child with someone else! Why would you do that?" After asking, Yu Zhenzhen felt a little foolish! She then murmured softly, "Why switch? Of course, it's to give my child a better life!"

Just then, Grandma Gong and Li Yunlu returned from the backyard. Li Yunlu was carrying a bunch of rose petals, her face showing reluctance. Grandma Gong smiled and said, "Yunlu, that girl, picked so many petals for Grandma." Li Yunlu placed the petals on the table, but her eyes remained fixed on Lin Jin and Yu Zhenzhen, wondering what they were talking about. Seeing Grandma Gong return, Yu Zhenzhen temporarily stopped questioning Lin Jin. Grandma Gong warmly invited everyone, "Don't just sit there, try some of my flower tea." Everyone picked up their teacups.

After finishing her tea, Lin Jin stood up and said, "Aunt Yu, Grandma, I'm so sorry, I have to go back home because I have something to attend to." Yu Zhenzhen was a little regretful, but still said, "It's alright, Dr. Lin, you go ahead and do your work." Li Yunlu, however, gloated from the side, "Oh, this country girl is so busy." Old Mrs. Gong glared at her, and Li Yunlu immediately shut up. After Lin Jin left in a hurry, Yu Zhenzhen was still pondering Lin Jin's words, "She felt that there seemed to be a big secret hidden in this, and this secret was related to her! If it's just a coincidence that she looks like her mother, but she also looks like her husband, then this matter needs to be investigated carefully!"
