What is a disposal sentence?

"Ba" sentence is also called disposal sentence.

The so-called disposal is to exert some influence on patients and cause some consequences. The patient of "ba" sentence usually has certain known information, and the disposal behavior and its result expressed by verbs and their complements are new information that needs to be emphasized. Generally speaking, Chinese doesn't like to put some known information at the end of sentences, which is one of the important reasons why Chinese VO sentences are not as commonly used as typical SVO languages.
