Hua Banzhi directly called Lin Xiyan to the laboratory.

Lin Xiyan walked into the laboratory and swept his eyes around, "This is a tool to increase traditional Chinese medicine." ”

"Do you know?" said Hana-branch, looking up at him.

"It's really hard for me. Lin Xiyan looked at the things on the experimental table, "The copper mortar for pounding medicine, the iron medicine grinding, and the ...... of the seeds"

The structure and principle of the pole are the same as those of the rod scale, and the part containing the object is a small plate, the largest unit is two, as small as cents or cents.

It is mainly used to weigh some precious gold, silver, jewelry, Chinese herbal medicine, etc., with grams as the unit of measurement, small weighing pan, thallium for brass or cupronickel.

The weighing rod has bone, ivory, horn, ebony, etc., and the best is the ivory rod, which is also of high value.

"The pole is the key component of the pole, where did you come from, the material of which is a tough ivory rod. Lin Xiyan looked at her with burning eyes and said.

"This ...... That ......" Hua Banzhi's eyes wandered, and he stammered.

Lin Xiyan looked at her with a weak heart, took a deep breath and said, "Say it! I'm not angry." ”

Hua Banzhi closed his eyes and muttered in his heart: What kind of strength do I have! Raised his eyes to him and said, "This was found in the thrift market." He looked at him clearly and said, "I know the road, and as for the language, it's not a problem." Changing the subject, he said, "The boss praised this very much, and said that it was very accurate, the same as the Western scale." The index finger pointed at him and said, "You said you wouldn't be angry." ”

Lin Xiyan could only pinch his nose and 'admit it' and follow her words, "Yes, this is as accurate as the balance in the West, and such a scale has been used to control the dosage of drugs for thousands of years." ”

"Qin Shi Huang unified weights and measures, and made an indestructible contribution to economic development and social progress. In the early years of the Eastern Han Dynasty, the wooden pole scale came into being, which became the premise and foundation for later generations to create the scale. China is the world's earliest ancient civilization to implement legal measurement, no matter from the ancient measurement accuracy, or from the measurement unit and measurement management system, it is unparalleled in the world. Lin Xiyan looked at her and said with a straight face.

Hua Banzhi looked at Lin Xiyan, who was possessed by the teacher, and would rather him popularize science than nagging himself.

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

"Since you want to make medicine, how can you do it without the tools at hand. Hua Banzhi looked at the utensils and said with a smile, "There is also a medicine cutting knife, that is, a guillotine." ”

"It's a press stool, you even have it. Lin Xiyan said in surprise with the strange artifact.

The so-called press stool is equivalent to the current juicer, where fresh Chinese medicine is put in it, and then pressed hard with a long pole, and the medicinal juice flows out from this side.

"And the medicated planer!" "A half-black ebony planer.

The medicated planer is equivalent to the planer used in woodworking, which is mainly used to process valuable medicinal materials, and deer antler tablets and gastrodia tablets are dug out with this planer.

"Your collection is quite complete, the pharmacy doesn't buy concocted medicinal materials, why do you bother to come by yourself. Lin Xiyan said and sat down.

"Everyone's method of concocting is different, but I'm more at ease to come by myself. Hua Banzhi leaned on the bench and said.

"You won't tell me that you have to go up the mountain to collect medicine by yourself!" Lin Xiyan raised his eyebrows and looked at her and said.

"I can't say for sure, of course I want to do it myself, but having a Chinese herbal medicine purchase shop can save a lot of trouble. Hua Banzhi looked at him and smiled.

"Ask an inappropriate question, concoction of medicinal materials is also a science, you ...... You ......" Lin Xiyan didn't want to hit her confidence, and she couldn't find a substitute for a while.

"No, I can learn!" said Hua Banzhi as she looked at him with a bright smile on her face, "Who will do it in the first place." ”

Yes, she was in the right state of mind, and she was in a hurry. Lin Xiyan said in his heart.

"I'm not at home, you confess honestly, what are you ......doing?"

Before Lin Xiyan's words were finished, he heard Chen Dali's loud voice, "Xiyan, brother and sister, are you there?"

"Chen Chu and Sister Qi. Hua Banzhi looked at him and urged, "Hurry up, hurry out." ”

Lin Xiyan looked at her and ran out as if she was running away, shaking her head funny, it was better for her to have a weak heart than to give herself another bill, that would really make her angry and vomit blood.

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

"Big change! I'll just say you won't recognize it. Second Sister Qi looked surprised and said with a smile.

"It's really impressive, I really don't dare to admit it. Chen Dali said truthfully.

"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, the fat is eaten, and there is no need to be exposed to the wind and sun. Hua Banzhi sat on the bamboo chair and looked at them and said modestly.

"Brother and sister, thank you for taking care of the second sister and their mother and daughter. Chen Dali solemnly looked at Hua Banzhi and thanked him.

Hua Banzhi hurriedly said, "It's right to help each other." Said playfully, "What's more, Sister Qi and I are still classmates." ”

"Classmate?" said Chen Dali without meaning for a while.

"Literacy class!" Qi Ermei reminded him funny, squinting at him, "Why aren't our literacy classes serious students?"

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

"Then you're welcome. Lin Xiyan said treacherously, watching Chen Dali subconsciously clench his purse, and said funny, "I won't let you break the bank, I have to keep the money to support my nephew!"

Nephew, Chen Dali and his wife love to hear this.

"You don't have to pick a Sunday, tomorrow morning, please eat early in the teahouse. Lin Xiyan looked at him and said with a smile.

"Okay!" Qi Ermei replied busily.

"Yo! It's almost time, I'll send Zhizhi to school. Lin Xiyan looked at the two of them and said.

"Go, go, let's cool down here. Second Sister Qi looked at the two of them and waved.

&*&

Lin Xiyan looked at the bicycle path, "Let's go! I'll send you to school." "I watched Hua Banzhi sit in the back seat and pedal the bicycle and leave the house.

When passing by the playground, he looked at Zhou Guangming, who was playing wildly in the playground, and shouted, "Guangming." ”

Zhou Guangming turned his head when he heard the sound and saw that it was them, said a few words to the eldest girl, and then ran over.

"Uncle, are you going to send my mother to school?" Zhou Guangming looked at the two of them and asked.

"Are you going?" Lin Xiyan asked as he looked at him with a smile on his face.

"It's been a long time since I've sent my mother to school. Zhou Guangming immediately said.

"Let's go!" Lin Xiyan beckoned to him.

Zhou Guangming ran to the car and was hugged to the beam by Lin Xiyan.

"Hold on, we're leaving. Lin Xiyan rode out of the family home.
