How to treat the school rewarding students to honor their promises?

Recently, the news that a parent received a reward voucher brought back by his son from school and made him cash it has attracted many people's attention, and also caused a discussion on the impressive operation of the school. ..... In my own school experience, the school had a similar operation. Specifically, it includes three things: digging a pond in the park, going for a spring outing by the far country river, and getting up early in the morning to organize a volleyball match. 1, the most wonderful operation of the school in my memory is to organize students to dig ponds in the park. In my memory, the most wonderful operation of the school is to organize students to dig ponds in the park. ..... There is a park in my city. One year, our school organized us to go to the park. We were very happy at that time and thought we could have some fun. But in fact, the school asked us to dig a pond there ... Now the pond has become an artificial lake, and every time we go, we will recall the experience of digging a pond. 2. When I was in primary school, the school once organized us to go to the riverside for a spring outing in the outer suburbs, and I felt very scared afterwards. Spring outing is a very happy thing, but the school has been very cautious in organizing spring outing for fear of unexpected situations. ..... However, once in primary school, the school organized us to go for a spring outing by the river in the suburbs far away. Although we had a good time and the spring outing was very successful, in retrospect, we still feel a little scared. If something had gone wrong, it would have been really serious. The school once organized a volleyball match after the students got up in the morning, which made us speechless. In college, once the school organized us to have a volleyball match in the early hours of the morning. ..... At that time, students just got up, confused, and participated in the volleyball match in such a state, and the result can be imagined. Now that I think about it, that event was really wonderful. ..... Although these things make people feel wonderful, they have also become very interesting experiences in their students' experiences, leaving a very deep impression on them.
