If there are too many words, the audience will be distracted to read the words on PPT, so that some people will not hear your wonderful speech when you explain; The second is to write some interesting and meaningful things in college life, such as classmates, respect for teachers, class harmony, etc. Third, you can look for photos you have accumulated before, you can also make more photos, and you can also find classmates to provide them to you. In short, the picture should be easy to repair.
