Azi's golden lock

A'Zi's gold lock is a simple piece of women's jewelry whose importance lies not in its appearance but in the identity it helps establish. At Little Mirror Lake, Ruan Xingzhu finds it on the apparently lifeless A'Zi; matched with a distinctive mark on the girl's left shoulder, it reveals that A'Zi is the daughter of Ruan Xingzhu and Duan Zhengchun, a child they had sent away to be raised elsewhere. The lock turns an intimate family clue into the hinge of a painful recognition scene: Duan Zhengchun has attacked his own daughter without knowing who she is.

Appearance and Discovery

When Ruan Xingzhu rushes out holding the lock, Xiao Feng sees nothing remarkable in it. He has seen an almost identical lock on A'Zhu, but to him it remains an ordinary ornament. Duan Zhengchun's response is different: after examining it repeatedly, his face changes, and he asks in a trembling voice where it came from. The contrast between Xiao Feng's casual recognition of its common appearance and Duan Zhengchun's alarm signals that the object carries a private meaning he understands.

Ruan Xingzhu explains that she took the lock from the girl's neck. She also says that she had once marked the child's left shoulder, directing Duan Zhengchun to check for that identifying sign himself. The lock thus works alongside a second physical token of identity. Neither clue alone is presented as a complete explanation; together, and in the context of the parents' recognition, they establish who the girl is.

Recognition and Consequence

Duan Zhengchun enters the chamber and checks the young woman's shoulder. Xiao Feng cannot see the mark, but he sees Duan Zhengchun's back trembling. Ruan Xingzhu then identifies the girl as their daughter and reproaches Duan Zhengchun for killing a child he had not raised. The lock's revelation arrives at the moment when the couple believe the girl has died, so recognition does not undo the harm: it makes the consequence of their ignorance unmistakable.

Xiao Feng, who had treated the lock as an unremarkable ornament, now understands its role as an identifying keepsake. He infers that the parents left both it and the shoulder mark as signs by which their daughter might one day be known. His inference links the object to the girl's fostered upbringing and to the parents' failure to recognize her before the confrontation. The episode also establishes the contrast between the tangible clues and the knowledge they cannot guarantee: the tokens endure, but the people who should have understood them meet only after violence has intervened.

A'Zhu and the Unfinished Recognition

The lock also recalls A'Zhu. When Xiao Feng remembers having seen a nearly identical one on her, he is struck by the resemblance between the two pieces. As Duan Zhengchun and Ruan Xingzhu recognize A'Zi, A'Zhu weeps and leans toward the bed. Xiao Feng notices her distress but accepts her explanation that she feels sorry for the apparently dead girl; he does not understand what her tears imply.

The scene therefore gives the lock a second, indirect function: it connects A'Zi's revealed parentage to A'Zhu through the sisters' matching keepsakes, while A'Zhu's response suggests that the discovery has personal significance beyond what she tells Xiao Feng. The object itself is common, and the scene does not explain how the sisters' locks came to match. Its narrative force comes instead from the recognition it enables, the family history it brings to light, and the grief that gathers around what the characters realize too late.
