Add points
Firstly, I need to know the features and advantages of this product, which will be highlighted in the video. Secondly, I need to know in what scenarios elderly people will use additional features. For example, their proposed magnetic components and detachable handles. This helps me better showcase them in the video. Then, how the image of the "little emperor" in their plan interacts and matches with the walking of the elderly after improvement. This helps with visualization in videos. If there is any additional content that needs to be added, we will post it on the website. Looking forward to and thanking you for your reply.
