Is there a word limit for the publication of American articles?

There is a word limit for the publication and discussion of American articles. I didn't think so at first, but I couldn't help writing a lot. As a result, I found that there was a word limit and I couldn't write any more. But I was in the period of inspiration in generate, and later I had to give up talking, so I wrote an article. I really tried several times. At first, I just wanted to write a speech, and finally I wrote an article because of the limitation of words. I also looked at the word limit of American articles, which seems to be 140 words, so if you want to publish articles, pay attention to the word limit of 140 words.
