Why can Chinese characters be written in one or two words, but Korean needs a long string?

Korean is an adhesive language, and every word should be followed by auxiliary words and suffixes.

For example, you can add an auxiliary word after a noun to make it a subject or an object.

Adding suffixes to verbs can make verbs have different states, causative and passive, modern past and future.

There are also auxiliary words to express more meanings and so on. .

So a complete Korean sentence is longer than Chinese ~
