My personal experience is that there are many types of entries, so find a classification that I like. You will find that there are still quite a few that have not been created. Or you can look at what types of entries other experts have created to imitate learning.

give examples: hot news events, hot words, people,
TV series
movies
music
literature
poetry
subject terms
and so on. A lot.
