This project was proposed many years ago. At that time, there were already many large tower fans. If it could be miniaturized, would there be a new sense of experience and refinement? When the concept was proposed, Party A did not have any understanding and experience of tower fans, so it refused. Then, by chance, Party A came to our company one afternoon. When I put forward the concept again, I was moved by it. After that, it sold very well. Basically, it was hard to find a product. In the second year, I made the mini version. Besides, the appearance was a little fresher at that time, but later, it was found that the retro feeling was popular at that time, and then it turned into retro green when the color was mixed later.
