There is a bug in the space? That's called buff!

Yu Qinghong wondered why she asked that. What was this place called? But Yu Qinghong answered seriously, "Printing has always been stereotyped. Hand copying is too inefficient."

Tang Yiran was shocked! Another business opportunity! If she promoted this movable type printing, wouldn't the printing efficiency increase exponentially?

Since Dr. Li was here, Tang Yiran decided to go to Carpenter Tan. The air conditioning issue had been delayed for a day.

Xiao Lei drove the carriage to send Tang Yiran to the door. With the sound of tinkling wind chimes, Tang Yiran walked into the shop full of sawdust again. The carpenter was as busy as ever, as if he was never idle.

The carpenter was very excited to see Tang Yiran coming, perhaps because he knew he could hear again.

Tang Yiran gave the air conditioner drawings to the carpenter, who immediately said there was no problem and pushed other work to do on the spot. Not long after, he made a sample: several rows of neat holes were punched on the thin wooden board, and the funnels were inserted into the holes. The other end of the funnel was replaced with mortise and tenon structure, which fit perfectly!

Carpenter Tan was very curious about this thing and asked what it was used for. Tang Yiran wrote: Cooling!

The surprise in Carpenter Tan's eyes was very obvious.

Tang Yiran was very satisfied with the air conditioner, and immediately asked Carpenter Tan to carve some commonly used Chinese characters on it, and wrote: "Don't worry, come back in two days to pick it up."

The carpenter nodded after reading it.

Tang Yiran paid for the air conditioner and the credit card together, and decided to go back and try out the effect of the air conditioner.

Xiao Lei drove Tang Yiran back to the Tang Mansion. After some tinkering, Tang Yiran finally installed the ecological air conditioner.

Xiang Ming and Leng Yu both found it magical. They felt much cooler instantly after installing the air conditioner. Ling Jun also leaned over to look at this thing curiously.

"Mom, what is this thing called?" Lingjun asked in a baby voice.

Tang Yiran touched Lingjun's head lovingly and said, "This is called an air conditioner!"

Lingjun nodded, not quite understanding: "Air conditioning, great!"

After lunch, Tang Yiran planned to return to Concordia Hall. Lingjun did not take a nap and insisted on following Tang Yiran to Concordia Hall. He also made a promise to Tang Yiran that he would be obedient. Tang Yiran had no choice but to accept, but finally he couldn't resist and took Lingjun with him.

As soon as he got off the carriage, Lingjun jumped into the Concord Hall. Yu Qinghong saw Lingjun at a glance. He looked a bit like Tang Yilan, with a pink and tender complexion that was particularly lovable. As soon as he entered the door, he blinked his dark eyes and looked around curiously, looking here and there, very curious!

"How cute!" Yu Qinghong exclaimed sincerely. It's not the kind of cuteness that comes from loving the whole thing, but the cuteness that comes from the inside out. Thinking of this, a motherly smile appeared on Yu Qinghong's face.

Ling Jun immediately noticed Yu Qinghong who was paying attention to him. He stepped forward and touched Yu Qinghong, saying in a childish voice, "Uncle, you are so beautiful, as beautiful as my mother!"

Tang Yiran walked into the door of Xiehe Hall at this time. As she walked in, she pretended to be angry and said, "Lingjun! Why did you touch uncle's face as soon as you came in? It's rude!"

Ling Jun immediately took his hand away and said apologetically, "I'm sorry, mother! I just think this uncle is very handsome and kind!"

Yu Qinghong immediately smiled and picked up Yu Qinghong and said, "It's okay! I don't mind!"

Then Yu Qinghong touched Lingjun's nose and asked lovingly: "Your name is... Lingjun?"

Lingjun smiled and said, "Yes! That's the name my mother gave me, Tang Lingjun!"

Yu Qinghong held Tang Lingjun in his arms and said to Tang Yiran, "After you left this morning, Lin Xingyu came over and said that he had found a way to get saltpeter and would be able to deliver a batch in three days."

Tang Yiran was shocked when she heard this. So soon? It seems like she can start her second business soon!

Shopkeeper Lin said, "Boss, more than a hundred people came to ask for ready-made medicine today. I left their addresses and told them that they can deliver it to their door if needed. Please take a look."

Tang Yiran took it and glanced at it briefly, then said, "Well done. Did anyone sign up for the notice I posted yesterday?"

Shopkeeper Lin immediately patted his head and flipped through another notebook and said, "Wow! Look at my memory! Yes, I forgot about it when I was busy. There are 20 people who have signed up. The information is all here. I asked them to come over today if they are interested. It's almost time!"

As soon as Manager Li finished speaking, he heard footsteps coming in. He looked up and saw a woman in her mid-thirties with wheat-colored skin, a strong body, thick lips, a bulbous nose, and a pair of bright eyes.

Yang Qing immediately stepped forward and asked, "Excuse me, what can I do for you? Buying medicine or seeing a doctor?"

The woman pointed to the sign at the door and asked, "Excuse me, are you hiring here?"

Yang Qing nodded and said, "Yes, yes, are you signing up for your family members?"

Then he pointed at Tang Yiran and said, "This is our boss. You can talk to him directly!"

The woman immediately waved her hands when she saw this: "It's either for my family or I need to find a job myself. Don't you hire women here?"

Yang Qing stared at her from head to toe for a long time before hesitating and saying, "For this kind of job, I'm afraid a woman will..."

Seeing this, Tang Yiran immediately stepped forward and interrupted Yang Qing, saying, "Women can also do this job!"

Then Tang Yiran invited the woman to sit down and got to know her basic situation. It turned out that the woman's name was Qin Jindou. Her husband passed away years ago. She had a 60-year-old mother and two young sons at home. The oldest was only ten years old. No place was willing to hire a female worker of her age. She could only work as a laundry worker to supplement the family income. She saw the notice outside and came in to ask.

Tang Yiran asked, "Can this carriage be driven?"

Qin Jindou smiled innocently and said, "Hehe, to be honest, I have never driven a horse carriage, only a donkey cart, so it should be about the same."

Tang Yiran hadn't been there either, but the two should be about the same, so he passed this one. Tang Yiran continued, "We can take eight days off a month here, which means we have to work 22 days a month. If you take time off for special reasons, your wages will be deducted. If you deliver 300 pieces a month, you can get two taels of silver. For every extra piece above 300, I'll give you an extra ten cents. But if you don't deliver 300 pieces, you can only earn ten cents per piece that month, and you don't have to work the next month. Is that acceptable?"

When Qin Jindou heard about this good deal, she was amazed. She could get eight days off a month, and the more she worked, the more she would get paid. She immediately patted her chest and said, "No problem! Boss! I, Qin Jindou, will follow you from now on!"

Seeing this, Tang Yiran took out the drafted contract and showed it to Qin Jindou. Qin Jindou looked at it for a long time and then said in a low voice: "Boss! I can't read! Whatever you say is what it is, I believe you!"

Tang Yiran then realized that this era was different from the era she lived in. There were too many illiterate people in this era. She ignored this point and almost made a mistake. Otherwise, how could she deliver the express correctly without knowing how to read?

Tang Yiran then gritted his teeth and said, "Aunt Jindou, I'm sorry, you can't do this job!"

Qin Jindou was already planning how to spend the wages, but then a bucket of cold water was poured on his head.

"Why?" she asked in confusion, her already big eyes widening even wider.

Tang Yiran said embarrassedly: "You can't read. You don't recognize the address written on this thing. Aren't you afraid of sending it to the wrong place?"

Qin Jindou's face was full of disappointment: "Thank you, boss. I understand."

After saying that, he stood up and left.

Tang Yiran quickly changed the subject: "But..."

When Qin Jindou heard about the reversal, he immediately sat down and asked happily, "But what?"
