Who understands? He traveled through time with a high-spec spatial ability.

Qiao Jingjing went to the kitchen. Although her uncle's house was in poor condition and dilapidated, it was very clean and tidy.

The Lin siblings, who were chopping wood outside, looked puzzled when they saw the large horse-drawn carriage parked at the gate. "When did our family acquire such prominent connections?" they wondered.

As soon as I entered the courtyard, I saw my aunt and uncle talking with my grandmother and parents. My aunt has arrived!

"Aunt, Uncle! Brother Ming!" The two put down the firewood and went to the main room. "Isn't my cousin here?"

Lin Dazhu has a son and a daughter. His son, Lin Zhijie, is 16 years old, and his daughter, Lin Xiuli, is 14 years old. Lin Zhijie is of marriageable age, but Xiaogang Village is notoriously poor, so there is no hope for marriage in the short term.

"Your cousin is in the kitchen, go and help her. You two sisters can also have a chat."

Lin Xiuli trotted into the kitchen, her voice preceding her arrival, "Cousin!" She had always liked Qiao Jingjing, thinking she was a woman of her word and trustworthy. When they were little, she had accidentally broken something and, afraid of being scolded, had asked her cousin not to tell anyone. Her cousin truly hadn't uttered a single word. Over time, she had forgotten what she had broken, but she vividly remembered her cousin's unwavering silence.

Qiao Jingjing was currently gutting a fish. Today's food included fish, chestnuts, sweet potatoes, two slaughtered chickens, 30 eggs, 50 jin of rice, 20 jin of flour, and 2 jin of mushrooms. She hadn't brought any duck or goose eggs; they weren't openly raised, so how could they have appeared out of thin air?

For lunch, we had braised chicken with chestnuts, and a ring of flatbread on top. It was a pity we couldn't get the cornmeal out, otherwise it would have been even more delicious. We also had pickled fish, roasted sweet potatoes, stir-fried eggs with wild vegetables, mushroom and chicken soup, and some rice.

Just as she put the rice in the pot and put the fire on, preparing to fillet the fish, Lin Xiuli came in. "Cousin, do you have any pickled cabbage?" Lin Xiuli paused. "Ah? Oh! Yes, I'll go get some."

She turned around, took two steps, then stopped. "Hey, my sister, are you all better?"

The group in the main room were chatting, mostly Lin Cuicui talking. She recounted how she had been collecting herbs and selling mushrooms, and how she had discovered problems with the rice paddies and how she had improved the planting methods. She also mentioned that Daya had discovered two new staple foods that were edible.

Everyone was amazed, never expecting Daya to have such good fortune. But after a while, no one was in the mood to think about it anymore.

It smells so good! What did Daya do? It smells amazing!

Qiao Shiming hugged his grandmother and whispered in her ear, "Grandma, my older sister's cooking is incredibly delicious, you'll see soon enough." After being fed for a while, and having eaten well every few days since the family separated, the little guy had chubby cheeks that made everyone want to pinch them. Seeing his grandmother staring at him, he leaned closer and said, "Grandma, do you want to pinch my chubby cheeks? Here you go!" He looked so proud and generous that Grandma Li hugged him and kept calling him "my darling, my precious little darling."

After a agonizing fifteen minutes, the kitchen finally called for dinner. The table was almost too big to fit everything; after all, there was hardly any food on the table normally, as the villagers' tables were never very big.

Lin Xiuli found all the old Lin family's treasured earthenware jars and plates. One dish was braised chicken with chestnuts, topped with 10 flatbreads; the pickled fish, lacking Sichuan peppercorns, was served with dried chili peppers and hot oil, making it even more tempting with its bright red and oily appearance; the earthenware jar contained stewed chicken with morel mushrooms, another dish of stir-fried wild vegetables with eggs, 5 roasted sweet potatoes, and 5 steamed sweet potatoes.

When has the Lin family ever had such a sumptuous meal? They don't even get to eat those flatbreads normally. The group swallowed nervously, not only because they were craving it, but also because Qiao Jingjing's cooking was truly delicious.

"Grandma, come and try my cooking! I saved Grandpa's portion for myself. Everyone, please enjoy it! Otherwise, I'll think my cooking skills have deteriorated!"

Grandma Li picked up her chopsticks before everyone else started eating. The aroma was simply divine. After the meal, everyone patted their bellies and burped contentedly. "I never expected chestnuts and sweet potatoes to be so delicious! They're so soft and chewy, absolutely soft and chewy, sweet and delicious, truly wonderful! And these mushrooms in the soup are so flavorful! Cousin, you're amazing. Not only do you know so much, but your cooking is also so good," Lin Xiuli said lazily.

Lin Chih-chieh chimed in, "Yes, this is the first time I've ever had fish that isn't fishy. The fish slices are tender, smooth, and springy, with a refreshing sour and spicy flavor."

The Qiao family members recalled that they had similar reactions when they first tasted these dishes. Qiao Shiming proudly straightened his small frame, as if to say: I told you, didn't I? My older sister's cooking is delicious.

After a satisfying meal, Qiao Jingjing sat down next to Madam Lin. She believed her mother had said everything she could, and now it was up to her to step in.

"Uncle, what's the current situation with the fields at home? Can you tell me about it?"

Lin Dazhu replied, "It's still 7 mu of land, 5 mu of paddy fields and 2 mu of dry land. The rice has been harvested now, and the dry land is empty."

Qiao Jingjing nodded and said softly, "Does Uncle want to change his current life? Or is Uncle confident that he can lead the whole family to learn planting skills, and more likely lead the whole village out of poverty in the future?"

Lin Dazhu said excitedly, "How could I not want to! My uncle dreams of it. If there's a chance to change things, who would want to live like this? As long as there's a chance, I'll persevere no matter how hard or difficult it is."

"It's not that serious, Uncle. Actually, Daya could have easily sent over the seedlings she'd cultivated, or even prepared the sweet potato tubers for you. It's just that Daya hopes you can learn and master these techniques yourself. Maybe you'll know more than she does in the future. Giving someone a fish is not as good as teaching them how to fish. Giving you fish is not as good as teaching you how to fish, don't you think?" Qiao Jingjing said with a smile.

"Cousin, can I learn?" Lin Zhijie was more anxious than anyone else. He was 16 years old and could take on the responsibility of supporting his family on his own.

"Of course! Once our Lin family has learned it, you can bring along the villagers you know. As long as people are trustworthy, the whole village can participate."

The people are suffering so much. They toil all year, only to not even have a decent meal. I can't bear to see them suffer. My personal strength may be small, but if this knowledge spreads, one person teaches two, two teach four, and so on, I believe that one day, the number of people suffering from hunger and cold will be greatly reduced.

The first step in solving hunger has been taken. If it can be implemented by the county magistrate next year, the capital will know about it within two years. It is expected that within five years, at least 85% of the entire Daliang area will implement high-yield seedling cultivation or double-cropping rice, and some areas can even implement both simultaneously.

The key issues to address when suffering from the cold are keeping warm and protecting against the chill. Qiao Jingjing has already made plans: cotton, heated brick beds, charcoal, and ginger are all essential. If trade with the Qiang people of the grasslands can be established in the future, wool sweaters and wool trousers can be further developed.

Whether a dynasty prospers or not is never determined by the powerful and wealthy, but by the common people at the bottom of society. The truth is, 80% of the people possess only 20% of the nation's economic wealth—a fact that has remained unchanged throughout history.
