Every Spring Festival, students will certainly receive many lucky money from their grandparents, grandfathers and grandmothers. Many of our classmates don't know what to do in the face of so many lucky money: some students buy it in buy buy with lucky money, and they have developed the bad habit of spending money indiscriminately since childhood; Some students left the lucky money with them and accidentally lost it, which brought a burden to the family; Some students simply put the lucky money in the bank, which is inconvenient when they need it.

In fact, I have long had a wish that we set up a "lucky money bank" at school to save all the students' lucky money. On the one hand, it can control those students who usually spend money lavishly, help them get rid of the bad habit of spending money indiscriminately, and at the same time facilitate those students who need money; On the other hand, schools can deposit money in the bank and earn a lot of interest. We can use this interest to help those students who drop out of school because they have no money to study. If students can save much money, they will deposit it in the school's "lucky money bank", and then the school will deposit the students' lucky money in the bank, and return the principal to everyone when they graduate, and the interest will be donated to students with financial difficulties or people in disaster areas. Then we did something very meaningful.

To tell the truth, we have collected lucky money for more than ten years since childhood, at least several thousand yuan. If the average person deposits in the bank every year according to the 300 yuan, each student in the sixth grade can deposit 1800 yuan. Our school is small, with only 17 classes, two classes in Grade One and Grade Two, three classes in Grade Three, four classes in Grade Five and four classes in Grade Six. If there are 45 students in each class, students in class 17 will keep the lucky money in the bank for one year, and the annual interest rate will be calculated at 2.25% (the interest rate of the People's Bank of China).

(300× 2.25 ℅×1)× (45×17) = 5163.75 (yuan)

If the number of classes and students in our school remains the same every year, then our school will have a fixed interest income of 5 163.75 yuan every year. There are several schools in our town. If every school establishes small banks, their interest income will definitely exceed ours. If every student insists on keeping the lucky money in the "lucky money bank", the interest income of the whole school will be many times higher every year after five or six years. With this money, on the one hand, we can help those children who are out of school because of lack of money; on the other hand, when there is a natural disaster in our country, we can use this money to help the children in the disaster area, so that they can have a good learning environment like us (like last year's snowstorm and Sichuan earthquake).

For the prosperity of the country and the harmonious development of society. Students, act quickly, take out your lucky money and deposit it in the school's "lucky money bank" to give our love! The above is my little wish, which I hope will come true one day and make my own contribution to building a harmonious society.
