What's the difference between short stories, novellas and novels?

It is generally believed that short stories with a length of less than 20,000 words will be classified as short stories. In its characteristics, there is the so-called three unifications-one person, one place and one time, that is, reducing the role, narrowing the stage and shortening the time flowing in the story. In addition, although they tend to cherish ink like gold, it is generally believed that short stories should conform to the original definition of novels, that is, there should be enough details to describe them, which is by no means an abridgement or outline of novels.

Generally speaking, novellas with a length of 20,000 to 80,000 words are considered as novels that are easy to succeed. Because for people who are new to the creative field, writing long stories is easy to fall into the predicament caused by most plots, while writing short stories is either monotonous with too few turns or too many turns. At this time, it is a widely recommended suggestion to consider changing the original idea into a novella.

Novels are generally considered as novels with more than 80,000 words. The novel reflects a lot of things and is very rich in content. Too few words can't make a novel, but the words used in novels are the most uncertain and the gap between them is the biggest. There are hundreds of thousands of words, and there are millions or even millions of novels. This kind of novels can also be divided into short stories (generally between10-300,000), medium-sized novels (generally between 500,000 and 700,000), novels (more than 800,000 words), super novels (generally more than one million words) and giant novels (often with one million words).
