When writing a graduation thesis, it will be revised many times. The revised draft is 1, and the revised draft is 2 ... If you use traditional documents, such as word, you need to save several versions on your own computer, which is very troublesome to manage. If you use a graphite document, when you edit it, it will be automatically saved as a version. Of course, you can also create versions manually. In this way, for example, if you want to see the chapter deleted yesterday, you can turn to the version history, call up the document version at that time automatically saved by the system, and then copy the deleted paragraph again. In word, you can't restore it if you delete it unless you back it up manually.
