The Clavis Sinica learning system is designed to assist current learners of Chinese to have a smoother study experience and act as an introductory lesson for prospective students. As a prerequisite, users need to have a basic understanding of Chinese characters’ composition and structures for a thorough comprehension. This method is different from the existing approaches. It helps broaden learners’ vocabulary beyond their textbooks. Clavis Sinica delivers several advantages. First, by identifying the component, the student can quickly look-up an unfamiliar character in any Chinese dictionary. The component serves an indexing role in traditional Chinese dictionaries, like the use of the first letter of a word in an alphabetized English dictionary. The second benefit of training the student to identify the component within each character is to stress the semantic qualities of the component. Building a familiarity with these rational roots, which hint to the meaning of a character, can build a better understanding of what is being read whether the reader is familiar with all characters in a passage or not. If one is instantly able to subconsciously processes this semantic hint, it may also increase the reading speed in addition to strengthening reading comprehension. This should give the second language learner a more native approach to reading Chinese. Studies have suggested that those with strong reading skills process text not by the sounds of each individual word, but by the context of the words within a sentence. Chinese characters are more than just symbols; it is the epitome of Chinese nation's philosophy and thinking mode. Now we can respond to Leibniz's questions. First, according to our research, there are 218 components in Chinese characters, they make up thousands of Chinese characters, and each component has etymological meaning. Secondly, with Single-element characters, there are only thirteen basic structures in Chinese characters. Finally, Xu Shen's "Six categories" is too puzzling to understand. We simplified the Chinese character formation method into "pictographic three categories ": Intact pictographs (including pictographs and ideographs), Fragment pictographs (indicative), and Partial pictographs (including Signific-phonetic, Mutually Defining Characters and Phonetic Loan Characters), which can show Chinese character formation methods more clearly. The key to Chinese makes the complex Chinese character system clear and coherent. The fact that learners start with textbooks that teach conversations and correlated characters may help them increase the ability of to converse in Chinese, but the characters they learn from the conversations are not easy to remember. For example, in one textbook, there is a class about saying hello to the person you just met. The Chinese characters are unbelievably hard for starters to memorize. On the other hand, if you pick out one character you just learned today, then go to the products created by component, you will see more component-shared characters that are highly related to the one you learned. So, you come to the products with one character, and after an incredibly short amount of time, you know over ten related characters. According to Clavis Sinica's, Zero-based foreigners can master 2600 Chinese Characters and reach intermediate level in two years’ time.
