从起源上看,汉字属于自源文字,因而和拼音文字有着本质的不同,具体表现为汉字有着天然的理据性,它是认知汉语乃至客观世界的工具。汉字的理据性表现是有层次的,仅仅用传统的“六书”难以完善地体现这种层次性。汉字理据及其层次性为汉语教学等应用领域带来了新的课题。 From the point of view of origin, Chinese characters are self-sourced texts, so they are essentially different from Pinyin texts. Specifically, Chinese characters are naturally motivated and are tools for recognizing Chinese and even the objective world. The motivation of Chinese characters is hierarchical, and it is difficult to reflect this hierarchy simply by using the traditional “six books”. The motivation and hierarchy of Chinese characters have brought new topics for applications such as Chinese teaching.
