With the summer vacation approaching, we call on all the students at school to actively participate in volunteer activities.
Not only will these activities help us develop valuable skills and a sense of responsibility, but they will also allow us to make a positive impact on our community. We recommend some attractive opportunities, such as organizing community clean-ups, tutoring students, and visiting nursing homes. These experiences will enrich your summer vacation and foster personal growth.
Let’s make this summer vacation meaningful and unforgettable by giving back to society!
