Gu Nanxun led Lin Qing through the garden and back to the main building of the courtyard house. They passed through a series of exquisite doorways and arrived at the spacious and bright living room in the backyard.

The living room's decor blends tradition and modernity, featuring both classic wooden furniture and modern, comfortable sofas and appliances.

"Qingqing, look over there." Gu Nanxun pointed to the color TV in the middle of the living room.

"A TV? Is this the one I used to sign in on?"

Lin Qing asked in confusion, "How come I remember that my sign-in wasn't like this before? Could it be that I remembered it wrong?"

"It's not the one you used to sign in. Yours was black and white. This is the one I used to sign in yesterday. It's a color one."

Gu Nanxun explained with a smile.

"Color TV? Have color TVs been manufactured yet?"

Lin Qing asked in confusion.

"Yes, my country's first color television set was produced on December 26, 1970, by Tianjin Factory 712. However, in the following years, the production and development of color televisions were in a slow initial stage. Even now, the output and ownership of color televisions in my country are very limited, and black and white televisions are still the mainstream in the market. my country's television industry as a whole is still in its early stages of development, and production technology and capacity need to be improved. It wasn't until the 1980s, with the introduction of color television production lines and continuous technological progress, that color televisions gradually began to become widespread. So although color televisions are relatively scarce now, they are still available."

Gu Nanxun earnestly explained to Lin Qing, and after a pause, he continued, "This color TV was produced by Factory 712 in Tianjin, and the brand is 'Beijing.' Until last year, 'Beijing' color TVs had already achieved a certain level of production and market supply, so we can definitely use it."

"This is the legendary Beijing brand color TV! Brother Nanxun, you're amazing, how do you know everything!"

Lin Qing touched the television in front of her, then looked at Gu Nanxun with admiration, her eyes shining.

Gu Nanxun chuckled softly, a hint of doting in his eyes: "Silly girl, it's not as amazing as you say. I just signed up for the color TV, so I went to look up the information."

Lin Qing shook her head in disagreement: "No way! You just signed in yesterday, and you can already say that now? Besides, you renovated the house yesterday. You did so much in one night, how can you not be amazing? No wonder you overslept this morning! Brother Nanxun, did you not sleep at all last night?"

Lin Qing walked to Gu Nanxun's side with a pained expression and hugged him tightly: "Nanxun-ge, you are always so thoughtful and considerate. I can't live without you anymore, what should I do?"

Upon hearing this, Gu Nanxun patted Lin Qing on the head and said with a smile, "What? You're thinking of leaving me? I won't allow it. You'll never leave me in this life, no, in the next life, and the life after that."

Lin Qing rubbed her forehead against Gu Nanxun's shoulder. Her brother Nanxun couldn't even be fierce, so the hit didn't hurt at all, and it even tickled a little.

"Yes, I won't leave. I won't leave in this life, I won't leave in the next life, and the life after that, and the life after that, we'll never leave. We'll always be together."

Lin Qing nodded seriously and said, "I can't bear to leave such a good brother as Nanxun!"

"Yes, we'll always be together, forever."

Gu Nanxun hugged Lin Qing tightly and nodded seriously as he spoke.

"Alright, let's continue the tour! What else is there besides the TV?"

After a long while, Lin Qing stepped out of Gu Nanxun's arms and then continued to ask curiously.

"Okay, come this way!"

As Gu Nanxun spoke, he pulled Lin Qing toward the kitchen. As soon as Lin Qing entered the kitchen, the first thing that caught her eye was the brand-new refrigerator with a distinctive style of the era.

The refrigerator has a very old-fashioned design, with top and bottom doors, and is a classic white, though not as bright as the white of later generations.

"This is a Snowflake brand refrigerator. Snowflake refrigerators are one of the earliest refrigerator brands in my country. As early as 1956, the Beijing Snowflake Refrigerator Factory successfully developed my country's first domestically produced refrigerator. Like color TVs, it is rare but still exists on the market today."

Before Lin Qing could ask, Gu Nanxun explained first.

"Great! This summer we won't have to worry about things spoiling anymore, and we can also have iced drinks."

Lin Qing said happily that although she had a space where she could eat chilled food, she hadn't let the children enter the space since they were old enough to remember things, so some things were inconvenient to take out.

As Lin Qing spoke, she opened the refrigerator. The refrigerator was empty, but Lin Qing seemed to see a full container of food. Thinking of this, she couldn't stop smiling.

"Here, there's more!"

Gu Nanxun pulled Lin Qing out of the kitchen. As Lin Qing followed Gu Nanxun out of the kitchen, she asked curiously, "What else? Are there any appliances too?"

"Yes, it's an electrical appliance!"

Gu Nanxun nodded in reply.

"Let me guess what it is, could it be... an air conditioner?"

Lin Qing asked excitedly, her eyes brimming with joy.

Gu Nanxun smiled and shook his head. "No, but it's close enough."

"It's not an air conditioner, but it's similar to one. I know, it's an electric fan, right?"

Lin Qing asked with a smile.

Gu Nanxun reached out and patted Lin Qing's head again, then smiled and praised, "Our Qingqing is so smart, she guessed it right away."

"Brother Nanxun, what's so clever about this? You've already told me almost everything!"

Lin Qing shook Gu Nanxun's arm in dissatisfaction and retorted with a smile.

"I'm just giving you a simple hint. It's mainly because our Qingqing is so clever. Now that you've guessed the fan, can you guess what the other appliance is?"

Gu Nanxun smiled and pinched Lin Qing's cheek again, then asked with great interest.

"Let me think! We have a TV, a refrigerator, and an electric fan, what's missing?... A washing machine? It's a washing machine, isn't it, Brother Nanxun?"

Lin Qing's eyes suddenly lit up, and she looked at Gu Nanxun expectantly, asking, "If you ask me what I want most right now, it's definitely the washing machine. After all, I can cheat and use other things secretly, but I can't bring all the clothes in my space to wash them! Even if I pretend to, I still have to wash them at home. But with a washing machine, it's different. I can completely free my hands."

"See, I told you! Our Qingqing is the smartest."
