Hua Banzhi directly asked Lin Xiyan to go to the laboratory.

Lin Xiyan walked into the laboratory and glanced around, "This is a tool that has added traditional Chinese medicine and pharmaceuticals."

"Do you know?" Hua Banzhi raised her eyes and said, looking at him.

"This is really hard for me." Lin Xiyan looked at the things on the laboratory bench, "The copper mortar of the pounding medicine, the iron powder, the (deng) seed..."

The structure and principle of the slave are the same as the rod scale. The part that holds the object is a small plate, and the maximum unit is two, as small as cents or cents.

It is mainly used to weigh some precious gold, silver, jewelry, Chinese herbal medicines, etc., in grams, small weighing plates, and thallium is brass or copper.

The scale rod has bones, ivory, horns, ebony, etc. The best one is the ivory rod, which is also of high value.

"The ivory pole is a key component of the ivory pole. Your material is a tough ivory pole. Where did it come from?" Lin Xiyan said with a bright look at her.

"This...that..." Hua Banzhi said stutteringly with her eyes wandering.

Lin Xiyan looked at her guilty, took a deep breath and said, "Tell me! I'm not angry."

Hua Banzhi closed her eyes and muttered in her heart: Why am I guilty! I looked up at him and said, "This was bought in the fresh market." She looked at him with a clear look and said, "I know the way, and language is not a problem." She changed the topic, "The boss praised this very much, and it was very accurate, just like the Western balance." The index finger pointed at him, "You said you wouldn't be angry."

The wood has already been completed, Lin Xiyan could only pinch his nose and 'recognize' and said according to her words, "Yes, this is as accurate as the Western balance, and it has been using such a scale to control the dosage of drugs for thousands of years."

"Qin Shihuang unified the weights and measures, and made irrefutable contributions to economic development and social progress. In the early years of the Eastern Han Dynasty, wooden scales emerged and became the premise and basis for later generations to create different scales. Our country was the earliest ancient civilization in the world to implement legal measurement. Whether from the perspective of ancient measurement accuracy, or from the perspective of unit of measurement and measurement management system, they are unparalleled in the world." Lin Xiyan looked at her with a serious face.

Hua Banzhi looked at Lin Xiyan, who was possessed by the teacher, and would rather he be popularized than nagging himself.

"You even bought the medicine mill." Lin Xiyan looked at the medicine mill on the ground and said.

"Since you need to make a pharmaceutical product, how can you do it without a handy tool?" Hua Banzhi said with a smile as she looked at the utensil, "There are also medicine cutters, that is, guillotines."

"This is a stool, you even have it." Lin Xiyan said in surprise with surprise.

The so-called pressing stool is equivalent to the current juicer. Put fresh Chinese medicine in it and press it hard with a long pole, and the juice flows out from here.

"There are also medicine planes!" Flower half a branch of black ebony planes.

Medicine planing is equivalent to a planer used for woodworking. It is mainly used to process expensive medicinal materials, deer antler tablets and Gastrodia elata tablets are drawn out with this plane.

"You have a complete collection. The pharmacy doesn't buy prepared medicinal materials. Why do you work hard to do it yourself?" Lin Xiyan said, sitting down and saying.

"Everyone's method of making it different, I'd better feel at ease if I do it myself." Hua Banzhi leaned against the laboratory bench and said.

"You won't tell me to go up the mountain to collect herbs by myself, right?" Lin Xiyan raised her eyebrows and said to her.

"I can't say this. Of course, I hope to do it myself if I have the conditions, but having a Chinese medicinal materials purchase store can save a lot of trouble." Hua Banzhi looked at him and said with a smile.

"Ask an inappropriate question, making medicinal materials is also a science, you...you..." Lin Xiyan didn't want to hurt her confidence, and could not find a term to replace her for a while.

"I can learn it if I don't know how to do it!" Hua Banzhi looked at him with a bright smile on her face, "Who can do it from the beginning."

Yes! She was right in her mind, but she was anxious first. Lin Xiyan complained in her heart.

"I'm not at home, you can honestly explain, you still do it..."

Before Lin Xiyan could finish his words, he heard Chen Dali's loud voice, "Xiyan, brother and sister, are you here?"

"Chen Chu and Sister Qi and the others." Hua Banzhi looked at him and urged, "Hurry up, go out quickly."

Lin Xiyan rushed out as if she was running away, shook her head amused. It was better for her to feel guilty than giving herself a bill, which would really make me angry and vomit blood.

"Are you Comrade Hua Banzhi?" Chen Dali looked at Hua Banzhi in surprise.

"It's a big change! I just said you definitely can't recognize me." Qi Ermei said with a smile as she looked at him in surprise.

"I really should look at you with admiration for three days after leaving, and I really don't dare to recognize you." Chen Dali said the truth.

"Let's sit down and talk." Lin Xiyan came out and looked at them and said.

"Actually, it's nothing? It's just that the food is good and you're fat. You don't need to be exposed to the wind and sun. If you cover yourself with white, you can cover your ugly faces with one white." Hua Banzhi sat on the bamboo chair and looked at them with a modest voice.

"My brother and sister, thank you for taking care of the second sister and the mother and daughter." Chen Dali looked at Hua Banzhi solemnly and thanked her.

Hua Banzhi quickly said, "It is necessary to help each other." He said playfully, "What's more, Sister Qi and I are classmates."

"Classmate?" Chen Dali came over without any meaning for a moment.

"The literacy class!" Qi Ermei reminded him with a funny look, glanced at him and said, "Why are our literacy class not serious students?"

"Yes, yes!" Chen Dali said with a smile, "I will treat you to dinner this Sunday, and you will order the place."

"Then I'm not polite." Lin Xiyan said treacherously, looking at Chen Dali subconsciously tightening his purse, and said funny, "You won't let you spend money, you have to keep money to support my nephew!"

Nephew, Chen Dali and his wife love to hear these words.

"There is no need to choose Sunday. Tomorrow morning, I'll just treat breakfast to the teahouse." Lin Xiyan said with a smile at him.

"Okay!" Qi Ermei responded hurriedly.

"Oh! It's almost time, I'll send Zhizhi to school." Lin Xiyan said to them.

"Go! Go! Let's cool down here for a while." Qi Ermei looked at them and waved.

&*&

Lin Xiyan looked at him and pushed the bicycle lane, "Let's go! I'll take you to school." Seeing Hua Banzhi sitting in the back seat, riding her bicycle and leaving home.

When passing through the playground, he looked at Zhou Guangming who was playing crazy in the playground and shouted, "Guangming."

Zhou Guangming turned his head and saw that it was them. He said a few words to Da Ya and the others and ran over.

"Auntie, are you going to send my mother to school?" Zhou Guangming asked as he looked at them.

"Go?" Lin Xiyan asked at him with a smile.

"Go! I haven't sent my mother to school for a long time." Zhou Guangming said immediately.

"Then let's go!" Lin Xiyan waved to him.

Zhou Guangming ran to the front of the car and was carried to the crossbar by Lin Xiyan.

"Hold it tight, we're leaving." Lin Xiyan rode out of the family yard.
