The original meaning of "harmony" is "giving", which is a content word. The function word "he" is a loanword, which can be used as a preposition, conjunction and adverb. The relationship between "and" has not changed much since the pre-Qin period. After the Tang and Song Dynasties, the preposition "Yu" produced new meanings, such as "Shi" and "Jiang", but these new meanings disappeared in modern Chinese. The adverb "he" is a subordinate word of "ju" and a polyphonic word.
