Feng Mian smiled faintly and said nothing.
After a moment, Feng Mian said again: "Then Sister Lan, remember to keep this secret for me. It's still uncertain whether Gu Yuelin and I will be together. I don't want to cause trouble."
"Don't worry, I'm doing business with you now, my mind has been broadened, I really understand you."
"Thanks."
"Hey, why are you still thanking me? I feel like you're too polite, you don't look like a country bumpkin at all. If I hadn't watched you grow up, I would have even suspected that you were a different person."
Feng Mian smiled and said, "This is called a girl changes a lot when she grows up."
"Yes, yes. Girls change a lot when they grow up."
…
After Lu Lan left, Feng Mian replaced the bedroom light with the one she bought on Taobao.
The main reason is that today's black filament lamps are too bad. Not only do they consume a lot of electricity, but they are also not bright.
The LED light at the rear consumes less power and is brighter, which is much better than this one.
At night they used electric lights, which were much brighter than candles.
Gu Yuelin stared at the light again and again, and touched the switch again and again. Feng Mian found it a little funny.
She was a time traveler and was not curious.
It turns out that this is the reaction people today have when they use electric lights for the first time.
"How much electricity do we use in a month?"
"Each light bulb consumes 20 watts of electricity. Five light bulbs consume 1 watt each. If they are lit for an hour, it consumes about 1 kilowatt-hour of electricity, which is 1.5 yuan."
Gu Yuelin was stunned for a moment and said, "It's quite expensive."
After saying that, he quickly turned off the light.
"Let's use candles."
Feng Mian smiled and said, "It doesn't necessarily have to be 1.5 yuan. There are a few more households in our village using electricity today. If we distribute it to each household, it should be cheaper."
Electricity bills are expensive now, mainly because of high losses and chaotic charging models. It would be better if prices were clearly marked like they were decades ago, but unfortunately it is still too early to reform the electricity system.
"That's not cheap either. It's more than one dollar no matter how much you spread it out."
Feng Mian thought for a moment and said, "How about this, I'll replace these lamps someday, so you don't have to worry about it and light candles again. Actually, candles are not cheap."
"Changed it? Can it save electricity?"
"Well, go check the bedroom lights, those two are five watts."
Gu Yuelin went to the bedroom out of curiosity. When he turned on the five-watt lamp that Feng Mian mentioned, he was shocked.
"What kind of light is this? It's the first time I've seen it. It's so bright."
Feng Mian leaned against the door and smiled faintly: "The lamp was bought in the big city and sent from Haicheng."
The store on Taobao is actually located in Haicheng, so she wasn't lying.
Gu Yuelin looked at her for a moment, then suddenly smiled.
It wasn't the first day she acted strangely, he was used to it.
The contract said he was not allowed to ask, so he didn't ask.
He thought that if they had a future, she would tell him one day.
If there was no future, it would be difficult for him to find out her secrets.
"Why install it so low? And install it on the wall? I see other people hang it in the middle of the room."
Feng Mian said, "We need to read books at night. How can we read if we hang it in the middle of the room?"
Gu Yuelin used a large box for clothes as a desk and installed a lamp above the box, which was indeed convenient for him to read.
He smiled and said, "You are so thoughtful. Thank you very much."
Feng Mian rolled his eyes at him and said, "You still say I'm polite, but you're quite polite too."
