Some adults contract the disease and recover on their own without realizing it until their children are infected and the children's symptoms are more serious and they are sent to the hospital for examination, only then do they find out that the whole family has tested positive.

To say what the disease is, solid evidence must be provided. Simply estimating based on age groups is the most unreliable and cannot be called evidence.

The boy said: "There is a nodular shadow on the film."

What!

A large group of people all turned around to watch the movie.

The boy who spoke was very proud of himself for being the first to notice the problem. However, when he saw teacher Cao opposite him with the corner of his mouth curled up as if he was smiling, his body froze and he was stunned.

Doctor Cheng Yuchen and Cao Zhao could guess what was going on. The eyelids were turned up to reveal the whites of the eyes.

"It's not a nodule," Zhang Desheng said. "It's the shadows on the nipples on both sides."

In clinical practice, the shadow of the head is often mistaken for a nodule by inexperienced medical students and young doctors. Especially when the patient's posture is not correct during the X-ray and the two heads are not in a straight line, it is easier to misjudge.

...

...

When the people from the National Association pointed out this obvious low-level mistake, the people from the Capital were not happy. A group of people pushed the boy who spoke rudely and said: If you don’t understand, you can just shut your mouth.

The people in the National Association should be relieved: it turns out that the level of the people in Guodu is just like this, slightly worse than that of classmates Wei and Zhao.

Perhaps they could tell from the faces of the people from the National Association that their opponents were thinking, so the students from the Capital University of China were eager to bring out their school's top student: "Duan Sanbao, come out and speak."

Three treasures? It’s a bit of a rustic name. Is he a top student?

A name does not represent a person's ability. Zhang Desheng and the others looked over warily and saw the top student that Guoduren had mentioned.

I saw that boy, he was not short, but for some reason, it seemed as if he had never raised his head. His lowered head revealed his thick black hair, making him look more like a natural ostrich holding up a bird's nest.

The most surprising thing was that this nerd with the posture of a little old man, holding a notebook and pen in his hands from beginning to end, looked very much like Li Qian'an, a classmate in their class, who was touching his notes nervously.

Only people who lack confidence would hold textbooks and notes all day long for fear that they will not be able to remember.

Is this person really a top student? There's nothing interesting about his name, and there's nothing strange about his appearance. Is there anything fishy about this guy?

Zhao Zhaowei thought of Song Xuelin, whose pronunciation was as strange as that of a printer. The talented scholar Song at least looked like a top student. He walked leisurely with all the pride of a talented scholar. Xie is a humble person and he won't keep his head down to find his way all day.

"Sanbao, you say!" The people of Guodu became even more anxious, seeing that the eyes of the people from the National Association opposite were full of doubts about their academic master.

In fact, people in the capital don’t need to be anxious. As long as the students of Guoxie see that teacher Cao Zhao is from Guodu, they will not think that Guodu students have no ability. Zhao Zhaowei and his group waited patiently for their opponent to make a mistake.

Perhaps because of their modesty and prudence, Duan Sanbao's classmates were very slow in speaking, and it seemed that they would not speak without permission from someone.

"You go ahead." Doctor Cheng Yuchen spoke on behalf of Cao Zhao.

Duan Sanbao finally raised his head and said, "You can let them speak first, teacher."

When they saw classmate Duan reveal his true face, Zhang Desheng and the others booed: Why are you lowering your head if you're not ugly?

Classmate Duan looks a bit like the darlings in pediatrics, with a face shaped like a pretty girl's peach face, two eyes that are a little big and bright, and chubby cheeks that seem to radiate a childlike innocence.
