Cheng Zhou immediately heard that the cause of the disease had been found, and he quickly picked up the child and shouted: "Wang Sheng... no, no, Ping'an Xiao Shenyi, you've found the cause of the disease, hurry up and take a look at this child!"

  Wang Ping'an saw him carrying the child over and hastily said: "Quickly take the child out, he got sick because of staying in this house!"

  Cheng Zhou and Tong Yiyi were shocked, and quickly took the child out again. Chang Qingfeng was also shocked, saying: "Ping'an Xiao Shenyi, where did you get this from? How could the child's illness be caused by staying in this house? This is a new house!"

  Wang Ping'an patted the wooden bed and said, "It's related to the new house, is this a newly painted bed?"

  Chang Qingfeng nodded and said: "Of course, this is a new bed. I specially found the best carpenter to make it. The wood used is of high quality, and three layers of varnish have been applied!"

  Wang Pingan sighed and said, "The problem lies in this lacquer. The child has... hmm, it should be called lacquer poisoning. He has lacquer poisoning, which can develop symptoms very quickly, sometimes overnight!"

  Hou Xiu was in the house at this time, and heard Wang Ping'an say it was eczema. He hastily stepped forward and said: "It can't be eczema, I've seen a case of eczema before, that had blisters! This child doesn't have any blisters!"

  Wang Ping'an waved his hand, indicating that everyone should go out and talk. After leaving the house, he saw Zhao Bi and Lu Xiuzhi standing in the courtyard. He said: "Brother Zhao, do you still remember that book 'General Treatise on the Origin of Various Diseases' you read?"

  Zhao Bi's face turned red, and in front of so many people, he was a bit embarrassed. He nodded and said: "I remember, of course I remember. What, does Wang Xian want to see that book? I'll bring it for you tomorrow!"

  Wang Ping'an shook his head and said, "I've read it." He turned to ask Gou Xiu, "Have you read this book?"

  Hou Xiu's face was filled with confusion, and he shook his head, saying: "No, I haven't even heard of it, what book is that?"

  Wang Ping'an sighed and said, "That book has a discussion on eczema. I thought the child had eaten something wrong all along, so I kept thinking in that direction, but it turned out to be a mistake. It wasn't until we got here that I realized it was actually eczema!"

  "The General Treatise on the Source of All Diseases" was written during the Sui Dynasty, specifically during the reign of Emperor Yang of Sui. At that time, the world was in chaos and everyone was fighting for survival, so who had the energy to care about such things? Printing a book at that time was also very laborious, and if you wanted to promote it widely, it would take a long time. The period from the end of the Sui Dynasty to the beginning of the Tang Dynasty was only a few decades, which is not enough time to popularize a medical book, let alone during peacetime. How could it be done in times of war? It's already fortunate that this book wasn't burned by fire.

  Zhao Bi came from a wealthy family, and his family was also in the business of selling medicinal herbs, so they had this book at home. However, Gu Xiu was just an ordinary doctor who only practiced medicine locally and wasn't a famous physician. Neither financially nor in terms of ability could he obtain "General Treatise on the Aetiology and Symptomology of All Diseases", a book that only people from the upper class were qualified to read at that time. It's not surprising that he had never heard of it. Doctors back then would even keep their prescriptions secret, let alone a good medical book.

  Wang Ping'an said to Gou Xiu, "The symptoms of smallpox are not necessarily blisters, but may also be papules, fever, chills, headache, or even constipation or loss of appetite. These symptoms do not necessarily occur simultaneously, and sometimes only one or two appear. Now this child just has swelling and redness. So, relying solely on experience to determine the cause of the disease is not enough, you must also read more books!"

  He forced a wry smile and thought to himself, "I'd like to read more, but I need books to read first. The book you mentioned, I've never even heard of it, let alone read it!"

  Cheng Zhou held his little grandson in his arms and stood in the courtyard, listening to Wang Ping'an say: "Eczema? I've heard of this disease, but I haven't seen anyone get it. Is this disease easy to cure?"

  "Wang Ping'an smiled and said: 'It's not difficult to treat, Mr. Cheng can rest assured!'"

  Zhao Bi and Lu Xiu listened together, shaking their heads in unison, thinking to themselves: "Wang Xian-di, you're really a straightforward person, you should say it's hard to cure, only then will he appreciate your kindness!"

  In fact, modern paint allergies also occur from time to time. In daily life, people decorate their new homes and always open windows for ventilation before moving in after a period of time. This is actually a common sense. Of course, it can no longer be said that it's just about letting out the smell of paint, but there are more or less some reasons for this. As times change, various pathogenic factors are also gradually increasing and cannot be considered separately.

  Now that we've identified the cause of the illness, it's easy to treat. Chang Qingfeng asked, "What medicine should we take? Dr. Hu is just nearby, we can go to his pharmacy to get the prescription filled."

  Wang Pingan said, "No need to be so troublesome, just use a wooden persimmon decoction and wash it off. Hmm, this is a bit of trouble, the old willow tree bark can also be used to make water for washing, but both are slightly slower in taking effect, and the child will suffer more. Dry lotus leaf or willow leaf... Ah, I have it, whetstone mud will do too, do you have a whetstone here?"

  Chang Qingfeng said: "Of course, this is not a banquet, yesterday I sharpened all the knives at home."

  "Let's go to the kitchen!" Wang Ping'an returned to the kitchen, where he saw a large bucket containing many crabs. The dish was prepared to thank the guests who came to congratulate them. He smiled and said: "Actually, taking live crabs and applying the yellow stuff on the child's body would work too, but that's also quite troublesome. Let's just crush these crabs with their shells and apply the juice to the child's body, this illness will be cured by tomorrow!"

  Hou Xiu was shocked and exclaimed: "Is it that simple? The last time I treated a case of eczema, I used a lot of effort!"

  Wang Pingan said, "Actually, this is a prescription... uh, one that I came up with myself. Bring me paper and pen!" He called for someone to bring over the four treasures of the study, picked up his brush, and wrote out a prescription. "I call this prescription Sanbai San," he said. "It's most effective in treating eczema. You can make a batch as a regular stock, and next time you encounter eczema, just use this medicine directly - no more flailing about!"

  He handed this side to Chang Qingfeng and said: "This can be considered as a small congratulatory gift I gave to your family, Brother Chang, for the great joy!"

  Chang Qingfeng took the prescription, cupped his hands and bowed to Wang Ping'an, saying: "Thank you, Ping'an, little divine doctor. If I hadn't met you today, I would have been too ashamed to face my old friend!"

  Cheng Zhou said, "Older brother Chang, don't say such things. Life is full of unexpected events. Our many years of friendship, I was just anxious and lost my composure earlier. If I said anything serious, you'll have to forgive me!"

  Two old men grasped each other's hands tightly, unable to hold back their sighs. The Chang family had servants who crushed the crabs into a pulp and applied it to the child's body. The guests who came to the banquet were also deeply moved, but only Hou Xiu stretched her neck and stared with wide eyes, wanting to take a look at the prescription, but she didn't dare ask Wang Ping'an for it, nor did she dare ask Chang Qingfeng, so she could only anxiously wait by herself.

  As things were almost done, Wang Ping'an was about to leave when Chang Qingfeng grasped his hand and said: "Ping'an, little divine doctor, on the day of my son's great happiness, you must come drink a cup of joyful wine! You absolutely must come!"

  Wang Ping'an smiled and said: "Good, I'll definitely come!" After a few pleasantries, he took the two little maidservants and left with Zhao Bi and Lu Xiu.

  After leaving the door, Zhao Bi complained: "Although Mr. Chang is a person from the Stab History House, his family has had an accident, and even if we didn't help, we still ran back and forth, but he actually didn't invite us two, really not giving face!"

  Lu Xiuzhi retorted: "What are we to him? He's an official, even if he wants to invite us, he can only invite our father, why would he invite us?"

  Wang Ping'an laughed and said: "He didn't invite us, I'll invite. Let's go back to the wine tower and have a big feast, good wine and good dishes are waiting for us!"

  After sending off Wang Ping'an, Chang Qingfeng rushed to the guests and said: "Everyone, I'm sorry. Today's auspicious time has passed, and we can't get married. We have to change the date. When we set another auspicious day, I will invite you all again. Today can only be abandoned. I apologize to everyone!"

  Everyone said: "Mr. Chang, don't be like this, things in the world are unpredictable, and it's inevitable that there will be accidents. Once we've settled on a date, we'll definitely come again to drink a cup of celebratory wine!" Each person gradually dispersed.

  Cheng Zhou saw that the swelling on Little Sun's body had subsided a bit, and he was delighted in his heart. It seemed that this method really worked. Seeing that his old friend still looked worried, he asked: "Is there still something troubling you?"

  "Others are easy to say, it's okay to come another day, but I've already sent out the wedding invitation to Governor Cishi. Now that we've changed the date, I have to go inform him, otherwise wouldn't that be a huge breach of etiquette!"

  Cheng Zhou nodded and said: "Will Governor also come?"

  Chang Qingfeng's face showed embarrassment, and he said: "The governor is busy, whether he comes or not, I don't dare to argue. But for the matter of changing the date, if I don't go and say something about it, it would be impolite, after all, I am his subordinate!"

  Cheng Zhou nodded and said: "Yes, you're right!"

  Chang Qingfeng said: "Today's matter is all thanks to Ping'an Xiao Yisheng, he is your student, how has his studies been lately?"

  This time, Cheng Zhou's face turned awkward, and he said: "I owe this young man a bit, I'll make it up to him in the future. He's going to take the medical exam, and judging from today, passing the exam is already a certainty!"

  Chang Qingfeng nodded and thought to himself, "Since he will definitely pass the imperial examination in the future, shouldn't I mention it to Governor Cui and let him take care of him? Alas, as a small official, I don't have that kind of face. However, Ping'an Xiaoyi is a good person, if Governor Cui asks why the wedding date was changed, I'll find an excuse and definitely talk to Governor Cui about this matter!"
