The park is really towering. In addition to a mountain trail, surrounded by all kinds of plants, flowers, trees, it is simply full of green. There is an air corridor here. People walking on it can directly touch the plants, which can be regarded as close contact and close-range explanation. This knowledge is not only the empty knowledge and the text on the books. Pretend to be in aerial photography on the air corridor, take the road below and the people who passed by. It happened to be a group of small and medium-sized students. I heard that every Friday is their outdoor teaching time, and the teachers will take these children out to teach on the spot. This feeling is great, you don't have to be limited to the knowledge in the classroom, you can really get close to nature, and naturally it won't be the end of the paper. It would be great if we had such a lively class every week in our elementary school.
