As stated in the "Customs of Ancient Chinese Costume", "Why do we call a ring a decoration like a ring?" It starts with the meaning of the word "ring". The Ming Dynasty's "San Yu Ju Bi" records: "Nowadays, the secular world uses gold and silver as a ring, and places a woman's finger space, which is called a ring." According to the "Poetry" Note: 'In ancient times, concubines and concubines entered the imperial court with courtesy, and the women's history records the sun and moon, giving them rings to advance and retreat.'. When giving birth to a child, one should retire with a golden ring; As the ruler, enter with a silver ring and place it on the left hand; The one who is already in charge is on the right hand. No matter how big or small, remember it as a law, and those who are known as the "ring" in the secular world will have their own way The Dictionary of Modern Chinese Word Names also cites a paragraph similar to the one above and says, "On the day of menstruation, a concubine wears a ring, indicating that she cannot have sexual intercourse with the emperor. The ring means' abstaining from sexual intercourse '. The "ring" and "ring" items in the "Chinese Dictionary" also cite the above statement.

Actually, not only the term 'ring' can be used to explain it. The other names of the ring also stem from this and can be used to explain it. However, due to different periods, the same reference to the ornament "ring" presents different titles. The word "Ji" in "Handji" is said in "Shuowen Yanbu" to be "Ji, Pi also." Paragraph note: "Pi, each of the original works is done in a sparse way... Pi, this word is done in a sparse way, which means to distinguish and recognize." "Handji" and "Ji" are combined to explain, "Handji" is a mark worn on the hand to distinguish and distinguish. "In connection with the previous quotation, the ring marks the progress and retreat of a group of concubines, whether in court or in court

The word "yue" for "yue refers to" yue "in" Shuowen · Bu ":" yue, tie it up. "Therefore," yue refers to "yue, tie it up on the finger. Why do we need to "contract things with fingers"? The reason behind this practice is actually to use the object as a "marker", and the contracted object is a symbol used by the concubines to avoid it. The "ring" characters for "driving ring" and "ring" are described in the "Shuowen Yubu": "Ring, Bi also. Good meat is like a ring." Here, "Bi" refers to "a jade wall with the diameter of the finger hole equal to the width of the surrounding area." Meat "and" good "are relative to" a circular jade wall with holes. "The outside of the hole is called meat, and the inside of the hole is called good." In the future, all "circular" objects are called "rings. So "drive ring" and "finger ring" are "rings worn on the fingers". Ancient emperors decided whether to be lucky or not based on their different wearing methods. The word "dai" of "dai zhi" in Shuowen · Renbu: "dai, even more so." Note by Duan Yucai of the Qing Dynasty: "Anyone who changes from this to that is called a generation... anyone who changes from one language to another is called a generation." The concubines of ancient empresses and concubines were not allowed to talk about menstruation, so they used the method of "wearing rings" to express it implicitly, avoiding the king's luck. So "referring to" can be understood as "wearing it on the finger as a substitute for speaking directly about lunar events
