This paper introduces the nature of the Chinese script, with the focus on its origin and development, the main four kinds of creation methods, the basic strokes of Chinese characters and the significance of its radical structure. The author believes that Chinese characters are the carriers of the script, phoneme and meaning as well as of the grammatical structure of the Chinese language. Hence, the Latin alphabet for the Chinese phonetic system cannot replace Chinese character, and learning Chinese character is very important for foreign learners. Finally, the author gives a mnemonic of the basic rules for stroke order that facilitates learners' memory and helps them write characters correctly and quickly.
