It's hard for my elder sister. I rely on the mountains to farm and pay off my debts.

Song Zhi smiled and put the spinning hammer into Song Huan's little hand, then picked up a small handful of combed wool and placed it on one end of the spinning hammer.

She patiently instructed her younger sister on how to gently hold the wool between her fingers and turn the spinning bobbin to gradually wind the wool around it.

"Yes, that's it, let it go slowly." Song Zhi's voice was gentle and encouraging, and her eyes were full of encouragement for her sister.

The child has always been shy and introverted and never asks anything of her.

It was rare for her to find something that interested her, so Song Zhi naturally didn't want to discourage her enthusiasm.

Song Huan was a little clumsy at first, but under Song Zhi's guidance, he quickly found the feeling.

Her little face flushed slightly because of her concentration and effort, and her eyes sparkled with excitement.

As time went by, a small ball of wool thread gradually accumulated on the spinning wheel in Song Huan's hand.

She said to Song Zhi happily, "Sister, I can spin yarn too!"

Song Zhi was not stingy with her praise and gave her a thumbs up, "Our Huanhuan is really smart. She learned to spin so quickly!"

Song Huan's face flushed with excitement because of her sister's praise, and her whole body was filled with joy.

The three boys who were playing outside heard laughter coming from inside the house and came over out of curiosity.

They stood at the door, poking their heads out, and asked curiously, "Sister, what happy things are you talking about? We can hear your laughter outside the house!"

Before Song Zhi could answer, Song Huan couldn't wait to pass the spindle in front of the others and boasted, "Look, this is the thread I just spun with wool. Isn't it amazing?"

After saying that, she also showed off the thread she had spun.

When the three of them saw this, their eyes lit up and they were immediately attracted.

They rushed over to see this new thing.

Song Huan took the opportunity to introduce to them how to use the spindle and demonstrated how to weave yarn.

The three of them watched with great interest, took the spindles with great interest, and began to try.

Although their movements were a little unfamiliar, they learned quickly and soon mastered the techniques and were able to weave yarn in a professional manner.

The children were very excited when they saw the yarn they had spun with their own hands.

To encourage their enthusiasm, Song Zhi promised: "If you can spin a bundle of thread, I will give you five cents."

When the children heard that they could get money, their eyes lit up and they worked even harder.

After arranging several young children, Song Zhiyi rushed to Dr. Zheng's house.

At this time, Doctor Zheng had already prepared the herbs that Song Zhi was going to identify today in the yard.

Doctor Zheng saw Song Zhi outside the door and waved to her, "You've come just in time. Before I introduce you to the herbs, I have something to tell you!"

"Medicines are divided into three grades: high-grade, medium-grade, and low-grade. High-grade medicines are mild, non-toxic or very slightly toxic, and can be taken long-term to maintain health. Medium-grade medicines may be toxic or non-toxic, and should be used with discretion, primarily to treat illnesses. Low-grade medicines are often toxic and should not be used lightly unless the illness is serious and urgent."

"I'm telling you this now because I hope you'll remember that medicine is life-threatening. Don't prescribe medicine recklessly when you're in doubt or unsure!"

Song Zhi listened carefully and promised solemnly: "Don't worry, Grandpa Zheng, I have kept your instructions in mind."

Wang came over with a tray and heard her husband talking about such a serious topic as soon as he arrived, which scared people away.

She couldn't help but say, "Azhi just came today, why are you talking about all this nonsense..."

After that, she handed the tea on the tray to Song Zhi, "Azhi, drink some sugar water to moisten your throat. Your Grandpa Zheng is like this. He likes to make a big deal out of anything related to herbs!"

Doctor Zheng glared. "Why are you making such a big deal out of something that involves life?"

Song Zhi hurriedly stood up and took the bowl. "Thank you, Grandma Wang, for the sweet soup. Grandpa Zheng spoke from the bottom of his heart. Ah Zhi will keep it in mind and will not dare to overstep her bounds."

After hearing what Song Zhi said, Doctor Zheng stroked his goatee with great satisfaction.

Worried that grandma would be angry, Zheng Hui on the side hurriedly persuaded Wang to leave, "Grandma, let's not disturb grandpa's teaching!" After that, she pushed Wang away and walked into the house.

How could Wang be angry? She was so happy to see that the old man was satisfied with Azhi.

She let her granddaughter push her back into the house.

In an instant, only Doctor Zheng and Song Zhi were left in the yard.

Doctor Zheng put his hand to his lips and coughed lightly, then continued, "Okay, now let me tell you about the over 700 kinds of herbs that have been discovered and compiled into books."

"According to the properties of medicine, it is divided into jade, plants, insects, animals, fruits, vegetables, rice, etc."

"Each type of herb has its own unique growing environment, medicinal value, and harvesting season. For example, this ephedra plant grows in the mountains. Its rhizomes are used as medicine to induce sweating, relieve exterior symptoms, and relieve asthma."

"And this licorice root is sweet and mild, it can harmonize various medicines, detoxify and relieve urgency."

As Doctor Zheng spoke, he picked up a few herbs and explained their properties and effects to Song Zhi in detail.

Among them were the herbs that I had introduced to her yesterday.

When Dr. Zheng got the herbs from yesterday, he would stop and ask Song Zhike if she still remembered the name of the herb, as well as its usage and efficacy.

Fortunately, Song Zhi had known these herbs before, so she was able to describe them smoothly.

Doctor Zheng nodded with satisfaction from time to time while listening to Song Zhi's narration. This child is indeed rare. At least she took note of it after returning!
