Jin Lixin believes that this is a means of alternation between voiced verbs and voiced verbs and the change of transitivity. He thinks that voiced sounds indicate the automatic meaning of intransitive objects, while voiced sounds indicate other meanings of transitivity: Hui: voiced sounds are automatic, yellow cuts jh, and now sounds Hu and Party. Cai Hou Zheng Bo will be in Deng ("Zuo Zhuan? The first year of Huan Gong); -voiceless, he moves, ancient cut outside. Jh, gold seal kuali, sum. At the end of the year, each will be based on its own content ("Zhou Li? Tian Guan's burial slaughter "). Solution: automatic voiced sound, humaiche, jinyinxi, and self-dissolution. Heaven and earth solve and thunderstorm ("easy? Xiegua "); -Silent, he moves and sells well. , gold and silver jiě, separate. My understanding of Wen is Hui Jun ("Zhuangzi? Health Lord "). See: voiced automatically, Hu Dian cut? Well, xiàn 'an, show me. Figure difference can also be seen ("Warring States Policy? Yan Ce); -.See xian Si Qi ("The Analects of Confucius? Establish a person "). Department: automatic voice, nonsense? Oh, golden seal, it's tied up. Tied for the golden rooster, judo cited also ("Zhouyi? Hey "); -.Silk Division ("Mandarin? Zhou ". Bad: automatic voice, Hu Guai cuts jh, now Hu Ai, self-destruct. Fast people have bad statutes ("Xunzi? Rough "); -Silent, he moves, the old is bad. Jh, always read guài, destruction. Bad palace thought dirty pool ("Mencius? Teng Wengong "). Therefore, the meaning of "harmony" of "hui" may come from the causative usage of "hui".
