The Chinese characters are now divided into two forms: Simplified Characters and Traditional Characters. The simplified form is used in Mainland China and has been recognized as an official language by the United Nations; the traditional form is used in other countries (Japanese, Korean, and Vietnamese....) and some regions.
These different writing forms make Chinese so complicated and discourage many learners. In fact, both forms are composed of mere 20-30 strokes. However, there are only six basic strokes; others are developed from the basic strokes. One can easily remember Chinese characters via strokes.
