What is the content of Jing M.Guo's composition for Happy Camp?

The content is as follows.

We designated March 5th as Lei Feng Learning Day. Now everyone is following your example, trying to do every little thing well and helping others as much as they can. You must be happy to read this, right? Don't talk about others, just say that there are many "living Lei Feng" around me! The first "living Lei Feng": Teacher Li, our senior class teacher, has been teaching for 22 years, which is considered an "old qualification" of the school, but she is more like our mother and takes good care of us.

Just recently, when Miss Li was talking to me, she came across a stitch on my coat. Without saying anything, she immediately rummaged through everything for a needle and thread. This is not an exaggeration. Miss Li really forgot where she put the needle and thread, because her drawer is full of our manuscript paper and homework. Then carefully sewed up the broken part for me. The second "living Lei Feng": Chen Yi, my classmate in the front seat, is very helpful even though his grades are not good. Being helpful has become a habit.

For example, once I quarreled with him and dropped my pencil case, he picked it up reflexively and bent down to pick it up in one go. I didn't even have time to talk. Of course, it would be more perfect if he could make the pencil case go straight back to my desk instead of flipping it 720 times in the air. The third "living Lei Feng": Ding Rui, the vice monitor of our class, is our vice monitor. We all call him "Nail". Although the temper of nailing is really as stubborn and hot as nailing, it does not affect him&; Elementary school composition. Recently, the "foot injury trend" in our class has passed, but the "flu storm" has struck again.

Students ask for leave one after another, either this or that. That's not true. Today, two people were carrying useless plates. As soon as our lovely and respectable nail monitor saw it, he immediately picked up the git and went straight to the canteen. The fourth "living Lei Feng": the eldest sister after 90. I don't know this sister, and I haven't talked to her, but she left a deep impression on my mind.

That time I went to class by bus, which happened to be the evening rush hour. The bus is so crowded that many people can't squeeze into the front door to pay by credit card. And that big sister is close to the credit card machine, so she helps others to swipe their cards again and again, tirelessly, without saying a word of complaint. Hum, who said that the post-90s generation was not enthusiastic enough? Uncle Lei Feng, did you see that each of us is trying to create a beautiful home, learning from you and doing our best! I wish you happiness!
