Is the beginning of a catastrophe? The little farm cook is raising a family with a full warehouse.

Although she did not accept Ji Yanchuan's invitation to go with her, Cheng Yuntao knew that Junhua City was no longer suitable for staying there.

The bone-chilling coldness surrounding her body reminded her that she had to pack her bags as soon as possible. Even if she couldn't reach Nanzhao in a short time, she had to migrate to the warmer south.

Thinking of this, she immediately began to organize her belongings seriously.

The rustling of winter clothes stacked in the bamboo box was suddenly interrupted by a heart-wrenching cough from the inner room. Cheng Yuntao's heart tightened, and she quickly put down the things in her hands and walked quickly into her grandmother Zhou Xiufang's room.

The cotton curtain was suddenly lifted, and when Cheng Yuntao rushed to the bed, she saw her grandmother Zhou Xiufang curled up in the mattress, her face pale, her lips blue-gray, and her chest heaving violently with her breathing.

"Grandma, what's wrong with you? Don't scare me!" Cheng Yuntao called out anxiously, her voice trembling. "She was fine yesterday, how come after just one night, she..." Cheng Yuntao became anxious when she saw her grandmother's haggard appearance. The last word broke in her throat before she could finish her words, and tears blurred her vision.

Zhou Xiufang opened her eyes slightly and looked at her weakly, her cracked lips trembling slightly. She was about to say something but was interrupted by a violent cough.

"Grandma, please don't talk for now and rest well." Cheng Yuntao's eyes were red, and she tried hard to hold back her tears. She sobbed and comforted her, "I'll go out and find a doctor right away. You will be fine."

Cheng Yuntao wiped away her tears, stuffed her grandmother's hand back into the quilt, and tucked it in.

As she hurriedly turned around, the wooden hairpin on her bun caught the tassel of the bed curtain. Without even bothering to straighten it out, she stumbled out of the door and grabbed Jiang Yu's wrist: "Quick! Jiang Yu! Go get a doctor!"

Jiang Yu's pupils suddenly shrank, and he didn't bother to ask too many questions. He took Cheng Yuntao's cold fingertips in his palm and replied hurriedly: "Huichun Hall is only a hundred steps away at the end of the alley. You stay with grandma, I'll go!" Before he finished speaking, he rushed into the streets where the cold wind was howling, leaving messy footprints on the thin frost on the bluestone slabs.

Soon, Jiang Yu arrived at Huichun Hall, but the closed door in front of him made his heart sink instantly. He slammed the door hard and shouted loudly: "Doctor! Is the doctor here?" But the only response he got was the whistling wind.

Jiang Yu was extremely anxious. He happened to see a passerby hurriedly passing by. He quickly stepped forward, grabbed the passerby's arm, and asked anxiously, "Brother, why is Huichuntang closed? Where is the doctor?"

A passerby was startled by his sudden action, then after collecting himself, said, "Don't you know? Those in the city with a little more money and a bit more courage have all headed south. The doctor from Huichun Hall was no exception; he left yesterday. Almost a third of the city's population has left now, and everyone's trying to find a way to get to warmer places!"

Hearing this, Jiang Yu's heart sank, but he didn't give up. He turned and ran towards other parts of the city. In the cold wind, his figure shuttled through the streets and alleys. He didn't know how long he ran before he finally remembered the old doctor who treated Shaobing's leg last time.

Jiang Yu rushed to the old doctor's residence, full of hope. Seeing the familiar door half-closed, he felt a surge of excitement. He stepped inside and breathlessly said to the old doctor, "Doctor, this is critical! Please come with me!"

The old doctor was a kind-hearted man. Seeing that he looked anxious, he immediately stood up, picked up his medicine box, and went with him without saying a word.

When she returned home, Cheng Yuntao was so anxious that her eyes were red. She paced back and forth in the house. When she saw Jiang Yu coming back, she hurried to greet him.

Jiang Yu explained simply, "The doctor from Huichuntang has already left. I was delayed a bit while looking for a doctor."

Cheng Yuntao knew he had done his best, and nodded gratefully. Then she said to the old doctor, "Doctor, my grandma keeps coughing and crying out in pain. Please help me."

The old doctor put down the medicine box and comforted her gently, "Don't worry, girl. Let me take a look first." As he said that, he quickly walked to Zhou Xiufang's bedside, first stretched out his hand to take her pulse, and then turned up her eyelids to check, with a focused expression and a slightly frown.

After a thorough examination, the old doctor straightened up, looked at Cheng Yuntao and Jiang Yu, and slowly spoke, "The old man's illness is mainly caused by this cold disaster. Ancient texts say, 'Where evil gathers, the qi will be weak.' The more severe the year, the more vulnerable people are to disease. The old man's lung qi is weak, and the cold evil invades, affecting the normal function of the lungs. His airway is blocked, and he keeps coughing and wheezing."

"The symptoms are very similar to those described in ancient texts as 'coughing and shortness of breath, with a sound like a water chicken in the throat.' This condition is common during cold disasters, and is mostly caused by the cold evil constricting the lungs." The old doctor patiently explained, "Fortunately, doctors have long had solutions. We can use methods to warm the lungs and dispel cold, relieve coughs and asthma, and combine this with moxibustion on acupoints like the Feishu and Tanzhong points for even better results."

"Also, joint pain in the elderly is called 'bi syndrome' in Traditional Chinese Medicine. It's primarily caused by cold and dampness invading the meridians, leading to poor circulation of Qi and blood," the old doctor added. "'The combination of wind, cold, and dampness causes bi', which is exactly the same principle. For joint problems, in addition to using prescriptions like Wutou Decoction to warm the meridians and dispel cold, you can also use acupuncture and moxibustion on the acupoints near the joints to warm and unblock the meridians and relieve pain."

"Don't worry, as long as you follow my instructions, the old man will definitely get better slowly." The old doctor finally reassured the two, "I'll write a prescription right away. Later, you can send someone to go back with me to get the medicine."

Cheng Yuntao said gratefully, "Thank you so much! If you hadn't come, we wouldn't know what to do."

The old doctor smiled and waved his hand, indicating that you are welcome. Then he turned and walked to the table, spread out the paper, picked up the pen, dipped it in ink, and quickly wrote down the prescription.

After a while, the prescription was written and he stood up and handed it to Cheng Yuntao.

Cheng Yuntao took it with both hands and saw the following words written on the prescription:

Xiaoqinglong Decoction, two cents of ephedra, three cents of cinnamon twig, three cents of peony, one cent of asarum, two cents of dried ginger... Wutou Decoction, two cents of Chuanwu, two cents of ephedra, three cents of peony... In addition, several medicinal herbs were prescribed to assist in regulating qi and blood and strengthening the physical fitness.

After reading it, Cheng Yuntao felt relieved and thanked the old doctor again.

As the old doctor packed up his medicine box, he said with concern, "Miss, during this time, you must let the patient rest and recuperate. Don't waste your energy or run around."

"Old people are old and their health is already weak. If they don't rest well, not only will their illness be prone to recurrence, but it may also leave a root of the disease. If they are not careful in the future, the symptoms will come back, and then it will be very difficult to deal with."

"We also need to pay special attention to our diet. We should try to eat light and warm foods to make them easier to digest. We must not eat raw, cold or greasy foods."

He looked at Jiang Yu again and added, "When decocting the medicine, you must boil the Chuanwu first and for a long time to minimize its toxicity, otherwise it will easily cause serious problems. The herbs in this prescription are all compatible and complementary to each other. No one can be missing, so you must be more careful."
