Abstract: “Gaozong liang yin”,recorded in documents of the Pre-Qin,means that Gaozong lived in a thatched cottage during his mourning period for three years and had not issued any orders. The term “liang yin” was based on the shape and form of the thatched cottage,imitating the residence of the deceased relative. The cultural and ideological connotation of the cottage form was the “yin du (experience)” the deceased relatives. “Yin du” is a widespread ideology and culture in ancient times,and its motivation is for one's feelings to overlap with the others'. While the “yin” in “yin du” and “wen” in “wen ren” both originated from the etymology of “yin” meaning overlapping,the “experience” between people,between people and objects,between people and nature was to measure one's feelings with that of others,and the essence of “benevolence” was to experience other's feelings,which was a connotation of the ideology and culture of “harmony between man and nature”. By comparing historical vocabulary with ones related to the same context,it is proved that some words' rhyme with closing vowels changed to nasal vowel(-m＞-n,-p＞-t/-?)in the pre-form-and-pronunciation era,taking “Yin阴” changed to “Yin隐” and “Wen温” as the manifestations of this changing type.

Key words: liang yin, loving, benevolence, experience others, historical pronunciation change, determining pronunciation according to meaning
