This little girl was also a member of the Feng Family; she must be the "very cute little sister" from that collateral branch that Feng Chi mentioned.
The little girl wore a zodiac amulet around her neck, and although it wasn't visible, Feng Yi had a sharp perception for amulets with patina.
The one she wore must have been a gift from her great-grandmother, highly similar to the one Feng Yi wore himself, crafted by the same person.
When he first saw her, Feng Yi had intended to give her one of those zodiac amulets, but sensing she already had one, he put the copper coin he was holding back into his pocket.
Feng Yi squatted down, his gaze nearly level with hers, and kindly asked, "Are you wearing a zodiac amulet?"
"Yes," the little girl replied, somewhat shyly lowering her eyes.
"I have one too."
Feng Yi curled his finger around the cord on his neck and showed her the zodiac amulet he wore, but he did not take it off.
