What's the difference between posting articles in headline number, micro headline and today headline?

This is a different product of today's headlines.

Micro headlines are like our daily diaries. There is no title and the length of the article is unlimited. You can write at will, without requirement or review. It is very similar to WeChat's circle of friends, and it is also like a buttoned space, mood and anything can be published.

The headline number is more like our composition at school, and we need to have a topic. The title of an article with a headline number is five to thirty words, and sensitive topics are not allowed. The same is true of articles, which can only be published after review.

I personally am such a difference between the two.

Please give me more advice. Thank you.
