TEX is a powerful background typesetting system, which was developed by Professor Donald E.Knuth of Stanford University. He is writing a book called The Art of Computer Programming. Because the publisher made the mathematical formulas in his book ugly, he decided to postpone the publication and developed a typesetting system for typesetting. This system is the Tex system.

Latex:

TEX is a very low-level typesetting language, which will be very difficult for most people to learn, and the typesetting work will become quite complicated, difficult to be used by more people, and the efficiency is not very high. Therefore, some commonly used functions, if defined in advance, can realize a relatively complex function only by quoting a short piece of code when necessary, which not only improves the typesetting efficiency, but also makes the layout much clearer. This predefined function is called a macro.

LaTeX is one of many macro sets of TeX written by Leslie Lamport. The purpose of writing is to separate the layout content from the specific content of the document as much as possible, so that the document writer can concentrate more on the writing of the document and spend less time on typesetting. So LaTeX is essentially a macro set of TeX typesetting system, which integrates some common functions into the settings of document types, simplifying the workload and difficulty of TEX typesetting.

TEX has many macro sets, LaTeX is one of them.

CTEX:

CTEX is the abbreviation of CTEX Chinese suite using TEX typesetting system. It integrates editor, WinEdt and PostScript processing software Ghostscript and GSview. CTeX Chinese Suite adds complete support for Chinese on the basis of MiKTeX. CTeX Chinese Suite supports two Chinese TeX processing methods: CCT and CJK.

Generally, people who use windows operating system will choose WinEdt software in CTEX as a tool to write LaTeX documents, because it will change the color of latex commands, integrate various commands into the graphical interface, and simplify the typesetting operation.

I hope I can help students who want to typeset with LaTeX but don't know where to start ~ ~

Once again, I recommend the introductory course "Let's learn latex", which is really vivid and detailed. Reference ~ ~
