Trainings on Character Writing for the Eighth Grade (Chinese) 

The learning of cursive and regular scripts should be started with the radicals of Chinese characters.Most of Chinese characters are composed of different components, which are called "sides".The meaning of a Chinese character is determined by its structure. Therefore, the same part should be used for reference, and such same part is called "radical".Since the sides and radicals are the basis for Chinese characters and feature a high popularity, it is an effective way to start with the learning of the sides and radicals.The mastery of a side and radical can help you understand more Chinese characters.
