本文认为，汉字产生的殷商时代，汉语已经有了明显的方言分歧。要使不同的方言由相同的文字来书写，汉字从一开始就需要保持在和表意相关的语素文字阶段。殷商以后，汉语方言的分歧仍然很大，汉字对书写不同的方言仍然是最有效的。现代汉语方言仍然存在很大分歧，需要用汉字来书写，拼音文字在汉语方言消失以前还不能代替汉字。用汉字书写下来的文本浩如烟海，难以用拼音文字转写，从继承文化的角度看，拼音文字也不能取代汉字。 This paper argues that in the Shang period of Chinese characters, Chinese had obvious dialect differences. For different dialects to be written in the same language, Chinese characters need to remain in the morpheme stage related to ideation from the very beginning. After the Shang dynasty, the divergences in Chinese dialects were still quite large. Chinese dialects were still the most effective for writing different dialects. Modern Chinese dialects are still very different and need to be written in Chinese characters. Pinyin scripts can not replace Chinese characters until they disappear in Chinese dialects. Written in Chinese characters voluminous texts, difficult to use phonetic transcription, from the perspective of inheritance culture, phonetic text can not replace Chinese characters.
