Regarding poster design, the following points can be considered:
1. Try to express your message with simple fonts and colors, which will make it easier for people to read your message.
Try to use pictures or simple graphics instead of words to express information, so as to attract more people to pay attention to your poster.
3. Keep the layout of the poster clear, and use large text so that it can be seen from a distance.
4. Pay attention to the choice of poster background, and be sure to keep it simple and elegant, which can make the content clearer and easier to understand.
Add the ideas you want to express on the poster to attract more viewers to be interested in your poster.
