How to fill in the label column of the third Canon Photography Competition?

You can fill in your own photos according to the theme, competition area, category, city scenery, still life, animals, major, talent, university and so on. I also sent a few photos of the competition. I feel that this label is mainly convenient for retrieval and search, and then it is convenient for website organizers to classify, which is not very important.

Pay attention to the use of keywords, not too long, concise and expressive, and use spaces between keywords to get by.

The photo size seems to be limited to 5 m.
