稚久九栀

'Zhi jiu jiu zhi' combines several Chinese phonetic elements into a poetic, abstract phrase that can be challenging to interpret directly without context. Generally, it brings up an association with longevity ('久(jiu)'), youth or innocence ('稚(zhi)'), and certain types of flower/plant life ('栀(zhi)'), such as gardenia, which can also imply simplicity and purity. As for foreigners trying to understand this nickname, they could infer an aspiration for long-lasting youthful qualities while maintaining inner purity, suggesting someone with a pure heart who remains fresh and youthful regardless of the passage of time.
