Pencil is also difficult. Although sun Yingying's medical skills are very good, he can't do anything else.

Finally, sun Yingying saw that her family bought a big white goose. Grandma Li was going to make an old goose pot. Suddenly her eyes lit up. She had seen someone write with a quill pen before. Maybe she could try it.

So sun Yingying came to the kitchen, pulled more than a dozen thick goose feathers from the goose, cleaned them and took them to the study.

The needle penetrates the small hole in front, hollows out the things inside, and then puts it in the ink. When it is loosened, the ink appears in the pen tube.

Then sun Yingying tried to write on paper. It was a little hard and not smooth, but it was much faster than a brush.

Sun Yingying repaired the other ones and polished them more roundly, which made them easier to use.

Sun Yingying found those soft and hard goose feathers that were suitable. She could absorb a lot of ink at one time and let her write a long paragraph of words. She was immediately delighted.

So when sun Yingying came to the Wu family medical center for treatment again, he took out a goose feather pen to write, which immediately attracted the attention of Dr. Wu, Xu Changhui and others.

It's just that they try to write with these pens, which is very difficult, because they are used to brush shoes and don't adapt to the hard goose feather pen head.

However, seeing that sun Yingying can write small and neat fonts and write quickly made Doctor Wu and Xu Changkui determined to practice writing with a quill pen.

In this way, you don't have to write a pulse, just a dozen. Just a short one; Long, two or three are enough.

Sun Yingying's pulse table is well written and neat. Every night, Dr. Wu looks it up carefully and can often feel surprises.

He also copied it himself and reported it to his family in Beijing.

In addition to the pulse cases with special treatment methods, there are also several quill pens and methods of use.

After a few days of practice, Dr. Wu has been able to skillfully use the quill pen, so the letter to the principal at his home is also written with the quill pen, which explains the advantages.

After 20 days of maintenance, Wu Shiniang felt that her skin was much better. Although the bronze mirror was vague and didn't really see it, Wu Shiniang's hands could feel the changes of her face and the elasticity of her eyes.

Even Dr. Wu kept praising. He felt that his wife was several years younger, had fewer wrinkles on her face, and her skin became a lot whiter than before.

Sun Yingying now especially misses the former mirror. If he can have a mirror, he can see his true face clearly.

To make a mirror, you need to make glass first. This is a very huge project, which was not easy to operate in ancient times.

Now he doesn't have anyone and doesn't have enough money to do experiments, so forget it. Sun Yingying decides to engage in her medical skills honestly.

These wonderful ideas will be discussed later!

Wu Shiniang saw sun YingYing and said, "Yingying, the skin care products you gave me before are really easy to use... Can you make more for me? I want to continue to use them. If the materials are very expensive, I can give you money!"

After hearing this, sun Yingying waved again and again, "although it will cost some money, these disciples can afford it! I'll pack the skin care products that Shiniang will use in the future!"

Wu Shiniang was not polite to sun Yingying on this point. "Then I'll thank my good disciple!"
