Issues with contractions of some parts of sentence formed with comparative form of prepositions bi in chinese language

Comparison sentences are used to express the difference in quality and level, high or low, when made with the help of bi prefixes. Basically two people, two objects, or differences in the levels of two states are compared. The words before and after the bi prefixes have the same properties and structure. If the words before or after the bi prefixes are the same, you can omit one. This article focuses on the fact that certain words are dropped when comparatively expressed with the help of bi prefixes, the changes that occur in the sentence as a result of the words falling, and the omitted words do not affect the content of the sentence.
