And this thing is not a consumable. A stethoscope can be used for several years, or even more than ten years without breaking.

So there is no need to put a lot of craftsmen on this and waste resources.

Just produce a small amount and gradually meet the supply!

"yes!"

Huang Yuan agreed with his hands.

"The common people would like to express their gratitude to His Highness the Crown Prince for the sake of the doctors and common people in the world!"

The creation of the stethoscope was a good thing for doctors and the people, and Chun Yuyi was very excited.

"There is no need to thank you. I made the stethoscope and sold it to the outside world. I did not give it away for free for charity!"

Ying Feiyu waved his hand.

Although a stethoscope is a small item, it does come with a cost, and it is impossible for him to give it away for free for a long time.

Didn’t all the people come swarming to receive it that day?

"This ordinary citizen naturally knows that as long as the stethoscope is developed, it will be a great thing for the people of Qin!"

Chunyu Yi surrendered again.

With a stethoscope, many diseases can be diagnosed more carefully without delaying the condition.

With symptomatic treatment, people spend less money and suffer less!

"Fine!"
Chapter completed!
