Shuowen: "The language is free, and there are eight sounds." It and the word "Zeng" are both "the book industry of Ci". The original meaning of the word "harmony", such as Zuo Zhuan Xi Gong Jiu Nian: "Does Xiao Baiyu dare to covet the life of the son of heaven without worship?" Xiaobai, the name of Qi Huangong, means: "I, Xiaobai, how dare I covet the life of a monk and not bow down?" Most of the annotations of later generations are interpreted as "aspect" by "Yu", which I have explained before, which is extremely wrong. "Zeng", the word Shu also; Yu, speak freely and agree. Moreover, the ancient sounds of "Yu" and "Zeng" are similar and have always been used as the meaning of "harmony". Of course, Yu Can also has the meaning of being used as "he". Zhang Taiyan used "Yu" as the meaning of "harmony" in the First New Dialect, which was a brilliant insight. According to "Er Ya Shi", "yeyu, body also." This is a self-proclaimed word that can be borrowed as "I".

(7) Flexible use of parts of speech-In ancient Chinese, the use of function words in content words, combined with the meaning of sentences, is often empty. Function words are practical and not fixed, so the flexible use of parts of speech is more prominent. It turns out that words created by working people according to specific things are all content words. The Yuan and Zhou Dynasties' Six Books of True and False said: "Generally speaking, the ancients created characters, mostly engaged in the beginning, and later rhetoricians took real characters as empty word to achieve their meaning ..." Today's empty word is full of ancient real characters. The so-called word is "invisible". It means that it is difficult to understand the meaning of a single word literally, and it is also difficult to find it in a dictionary. It must be understood in combination with contextual sentences in order to understand it. Therefore, in ancient books, the phenomenon of flexible use of parts of speech is manifested as: real and virtual, virtual and real, often changing endlessly, and it is difficult to grasp its regularity. For example, "Yu" is the first personal pronoun "I", but it is also used as a function word in ancient books. Ancient sound reading snake,
