After standing for a while, I saw Senior Brother Cao coming back.

Taking out a briefcase from the drawer, Cao Yong seemed to have prepared something for his fellow junior students.

Will it be a book? A ratings form? A comment form?

Several students' minds started racing and they couldn't help but think of Feifei.

With a squeak, the zipper opened, and like a slow-motion shot in a movie, Cao Yong took out a yellow object from his briefcase like magic and placed it on the desk.

The thing is about the size of a palm, has a round head, a plump body, and is bright yellow all over. It is very cute.

Is it a plastic yellow duck?

Several students blinked violently.

Cao Yong continued to dig, and took out three little yellow ducks, and placed them in a row in front of several fellow junior brothers and sisters.

...

...

Looking closely, they were indeed four little yellow plastic ducks. Their appearance was too familiar. They were clearly the kind of toys that children play with while sitting in the bathtub. There was a hole under the seat, and when you pinched it, it would make a quacking sound like a duck.

"You have been in the neurosurgery department for almost a week. This is a gift for you." Cao Yong spread out his hands with gentlemanly and elegant movements, and his words were full of instructions for his four junior brothers and sisters to take the gifts without hesitation.

Looking back, Senior Brother Cao was unusually generous. He treated them to a meal on the first day they came and gave them a little yellow duck in the first week.

For a moment, the four students felt like they were back in the pediatric department. In the pediatric department, the fairy brother treated them like children and never gave them any toys.

The four of them were very nervous. They had been waiting for half a day but didn't get any comments from Brother Cao, the teacher. Instead, what they got was four little yellow ducks. They were almost scared to death.

"Have the class monitors ever taken the little yellow duck before?" Wei Shangquan, the student who was least afraid to speak out, asked other students in a low voice.

"No." The other students shook their heads in denial.

Weird.

Senior Brother Huang came over and wanted to pick one up to have a look, but was glared at by Senior Brother Cao.

It can be seen that Brother Huang is not qualified to get the little yellow duck.

What do you want to take? Use your brain.

The above meaning was written in the look that Senior Brother Cao gave Senior Brother Huang.

Seeing this, several students stepped forward and took the little yellow ducks in front of them. The order of placing the little yellow ducks was particular, and each one was placed at the position where each of them stood.

Wei Shangquan seemed the most impatient. He picked up the little yellow duck and immediately pinched it. He was so excited that his mouth twitched. Geng and Pan, who were standing next to him, also twitched their mouths: "Please stop pinching it."

The question is, did Senior Brother Cao give them this thing so that they could pinch it?

The students turned over the little yellow ducks, and underneath each of them they saw the medical instructions written for each of them by Senior Brother Cao in oil-based pen.

Wei Shangquan recited his own: "Pinch it a hundred times a day."

Fearing that he would be treated specially by Senior Brother Cao, Wei turned around and looked at Student Geng next to him: "Wow, you pinch me 500 times a day!"

Geng Yongzhe's face darkened and he told the poor student Wei to shut up.

Student Wei was so happy that he couldn't think of anything else: Hahaha, this time he won.

Don't ask why, you can feel it intuitively that the fewer times Brother Cao asks someone to pinch, the less that person needs to exercise.

Then pull Pan’s hand and look at his little yellow duck.

"How come you only do fifty times a day? Less than me." Wei Shangquan complained with a pout. He had finally defeated classmate Geng and he thought he would win a great victory this time.

The corners of Pan Shihua's mouth curled up, as if he could see that Song Mao would not be very happy.
