Here is a breakdown of the name Ouyang Di-di (欧阳娣娣) , structured into the four parts you requested.

1. The Surname: Ouyang (欧阳)

“Ouyang” is not a single surname but a compound surname (复姓) , and it is historically regarded as the foremost of all Han Chinese compound surnames. Its literal components are 欧 (Ōu) and 阳 (yáng). In ancient Chinese geography, “阳” (yáng) referred to the south-facing side of a mountain or the north bank of a river, i.e., the side exposed to sunlight. The surname originated from a place name: a descendant of the Yue king was enfeoffed as the Marquis of Ouyang Pavilion (欧阳亭侯) at a location called Ouyang, situated on the sunny (southern) slope of Mount Ouyu. His descendants then adopted “Ouyang” as their clan name. So, as a surname, it does not carry a standalone lexical “meaning” in the way an ordinary word does; it is a toponymic identifier meaning, roughly, “the [people] of the sunny side of Ouyu.”

2. The Given Name Characters: Di (娣) and the Reduplication Di-di (娣娣)

The character 娣 (dì) is composed of the female radical 女 (nǚ) and the phonetic component 弟 (dì, “younger brother”). Its core dictionary meanings are relational and historically specific:

Younger sister: In classical usage, it denotes a sister who is younger than the speaker, or simply a younger sister in general.

A younger co-wife or concubine: In the context of ancient polygamous marriage, when sisters married the same man, the younger one was called 娣, while the elder was called 姒 (sì).

A husband’s younger brother’s wife: It could also denote the wife of one’s husband’s younger brother (a co-sister-in-law relationship).

A name-element with a “hoped-for-brother” connotation: In traditional Chinese naming practice, 娣 has frequently been used in girls’ names with the implicit or explicit wish that a younger brother (弟弟, dìdi) would follow. This association is culturally widespread, even though the character’s formal dictionary definitions are primarily kinship terms.

When reduplicated as 娣娣 (Di-di) , the name takes on an affectionate, diminutive quality, much like calling a child “little sister” or using a pet form. The reduplication softens the potentially formal or archaic tone of the single character and makes it sound intimate and childlike.

3. The Full Given Name as an Ordinary Lexical Item

As an ordinary vocabulary item, “娣娣” is not a standard, independent word in modern Chinese dictionaries. It functions as a reduplicated kinship term or a nickname-like form. If one were to treat it lexically, it would most naturally be understood as an affectionate reduplication of “younger sister” —roughly equivalent to saying “little sis” or “sis-sis.” In everyday speech, the unreduplicated 弟弟 (dìdi) is the standard word for “younger brother,” while 妹妹 (mèimei) is “younger sister.” “娣娣” is thus a name-specific, stylized variant that borrows the “younger sibling” semantic field but attaches it to the female character 娣. Its lexical “meaning,” therefore, is not a fixed dictionary definition but a pragmatic one: an endearing, sisterly diminutive used as a personal name.

4. The Origin of the Name “Ouyang Di-di”: Family Choice and Public Interpretation

Strictly speaking, “Ouyang Di-di” is her legal given name, not a stage name adopted later for professional purposes. In promotional materials for her short drama Bionic Lost Trail (仿生迷踪), she is billed under her original name “欧阳娣娣,” not a separate artistic alias. The “origin” of the name is therefore a family naming story, which has been publicly discussed because of its cultural associations.

Her mother, Fu Juan (傅娟) , has explicitly addressed the widespread assumption that “娣” was chosen because the family “wanted a boy.” Fu Juan has stated: “Everyone thinks I named her Ouyang Di-di because I wanted a boy; actually, I didn’t, not at all.” According to her account, the name was chosen to continue the pattern of her two older sisters, Ouyang Nini (欧阳妮妮) and Ouyang Nana (欧阳娜娜) , both of whom have reduplicated names with the female radical 女. When she was pregnant with the third daughter, relatives sent daily name suggestions. Two finalists emerged: 欧阳娣娣 (Ouyang Di-di) and 欧阳媚媚 (Ouyang Mei-mei) . Fu Juan asked a friend which sounded better; because Fu Juan’s own sister was named Fu Mei (傅媚) , the friend preferred Di-di, and the name was settled.

Despite this explanation, the name has remained controversial because “娣” in Chinese naming culture is widely associated with the “hope for a younger brother” (盼弟/招弟) tradition—the character contains the sound and semantic echo of 弟 (“younger brother”), and many girls named with 娣 historically came from families that had hoped the next child would be male. Fu Juan has also acknowledged that before the baby’s sex was known, she did initially hope for a boy, though she denies that this was the reason for the name itself. Thus, the “story” behind the name is a layered one: a mother’s stated intention to create a harmonious, sister-linked set of reduplicated names, overlaid by a broader cultural reading of “娣” that the public has found difficult to ignore.
