After school in the afternoon, everyone left the classroom in a hurry, only Yang Lezhen and Wu Shumei stayed in the classroom to study on their own.

Everyone had just finished leaving, and they all came back in a hurry.

"Did something happen?" Yang Lezhen asked.

"The head teacher has something to say to us, telling us not to go back to the dormitory yet." Wang Lu said as he sat down.

Most of the students returned to the classroom, except for a few who did not.

Teacher Wu walked into the classroom, she didn't care whether the other students had returned or not, as long as most of the students were sitting in the classroom, she had something to say.

"Students, now the weather is getting colder and colder, many students have told me that it is very cold to sleep in the dormitory, and the quilt they cover is not warm enough, and they want to close the door of the dormitory, but we always have to keep a little air."

"Today, I just wanted to buy cotton wool for some of our classmates, and I received a notice from the school in the afternoon, if you feel that your quilt is not warm enough, you can go to Teacher Liu on the second floor of the school's living building to get a bed of cotton wool."

"Of course I do." Lu Xianglan hurriedly said.

"Raise your hand if you need it."

A lot of people raised their hands.

"A total of 42 people need thick cotton wool, so you should hurry to the living building now!"

Wu Shumei saw that Yang Lezhen didn't raise her hand, so she asked, "Don't you need cotton wool?" ”

Yang Lezhen shook his head and said, "My quilt is so thick, there is no need to add thicker cotton wool." ”

"Then I'll go, you can help me pick a bed of better quality cotton wool!" Wu Shumei continued.

Teacher Wu saw that Wu Shumei hadn't gone yet, so he walked up to her and said to her, "Wu Shumei, Yang Lezhen, hurry up now!" Before 6 o'clock, the door of the living building is still open, and after 6 o'clock, the living building closes. ”

Yang Lezhen listened, smiled slightly, and said, "Teacher, I already have a bed of very thick cotton wool." She asked me to help her choose a good one, but I didn't know how. ”

Teacher Wu said: "The quality of these cotton wool in our school is very good, but you can help her pick a thicker bed, go now!" ”

"Okay." The two said in unison.

In the living building, the students lined up in an orderly manner, taking the cotton wool one by one, some students took the cotton wool and said thank you, while some students didn't know how to say thank you.

Yang Lezhen and Wu Shumei came to the living building, where there was a long queue, but it was orderly.

Ten minutes passed.

"Wow, there's a lot of cotton wool here!" Yang Lezhen sighed.

"With such a thick batting, I don't know if it can fit in my sheets." Wu Shumei asked herself.

At this time, Teacher Liu came over and asked her in Hunanese, "How big is your sheet?" ”

“2m6×1m1。” Wu Shumei thought about it for a while and felt that it was 2m6×1m1.

"The 2m6 ×1m1 ones are over there, not here." Teacher Liu pointed to the side of the window and said.

"How thick is that?" Wu Shumei just took two steps and turned her head to ask.

"It's at least 3cm thick, don't worry! All we provide in our school is very thick cotton wool. ”

"You cover it at night so that it's not cold, and if you need to study, you can also drape it over your shoulders." Teacher Liu said with a smile.

"Put on a thick cotton jacket, and you don't have to drape the quilt on your shoulders to study." Yang Lezhen said while laughing.

After Wu Shumei got the cotton wool, she happily thanked the teacher and left.

After that, Wu Shumei came back and said to Yang Lezhen: "Why are you still stunned, hurry up!"

"She hasn't picked up the cotton wool yet!" Teacher Liu said.

"I don't need cotton wool anymore." Yang Lezhen said embarrassedly, and then she also left here.
