Nature is a very complex biosphere. People often think that they understand nature enough, but in fact, people's understanding of nature is just a drop in the bucket. Often a plant appears in front of people, and no one knows its name and its function, etc. This shows how strange humans are to nature. Only by having more understanding of nature can they survive better on this earth.
For example, whether in the north or in the south, a flower that blooms like a skirt and a trumpet can be seen. Usually people just smile and appreciate it. If you really ask the name, few people know it. I know that one day I saw it on the Internet called Rose gourd. So what is it?
