The concept of 5% duplicate checking means that the duplicate checking rate is very low. Because in most colleges and universities, it is enough for undergraduates to set the duplicate checking rate below 30%. Then graduate students need to be below 20%, and graduate students in some schools need to check the duplicate below 10%.

Whether undergraduate or graduate, 5% is far below the relevant standards, which means that this paper is also very excellent.

There is no reference at all, and then in the official search center related to HowNet, all databases and all discussion libraries will be queried, so it is very strong to reach 5% in such a search center.

That is to say, this paper was completely completed by my own thoughts, and then completely completed by myself, so there is such an idea that such a paper with duplicate checking rate is likely to be regarded as a model essay.
