The study of Chinese characters has been refined through thousands of years. There are two major categories in general; the intensive method and the dispersed method. Starting from 1960s, a special Chinese character learning method, the "family word" study, was established. After 20 years of continuing research and development, this teaching method has been adopted broadly in Chinese word study, particularly, in the second and third levels of word studies, and utilized in diverse Chinese learning textbooks. Mr. Dachang Ji developed a "root word" system. It extends about 300 "word families" into roughly 800 "root words." The system makes the Chinese word studying faster, easier, and more efficient. This dictionary's content and the word searching system are based on the "root word" system, which sorts the three thousand most frequently used Chinese characters. This dictionary helps students learn Chinese characters quickly and conveniently. At the same time, it teaches learners to distinguish characters that look similar, but not the same in a repetitive manner. This dictionary also contains 119 poems and short stories, including famous poems from the Tang and Song dynasty, kid rhymes, words for daily living, and the 2,500 most frequently used Chinese characters. Through these and the convenient "root word" system, the dictionary will become a necessary tool for overseas Chinese learners. This dictionary functions as an important and indispensable reference book in Chinese word studying. It can be used along with a variety of Chinese learning materials that help the Chinese word and literacy learning faster and more efficient. The attached famous poems and reading materials demonstrate classic Chinese culture. Learners can read them repeatedly to improve their Chinese pronunciation and enhance their knowledge of the basic Chinese characters.
