Zhi Zhi's brand name consists of two words: TIAM (Persian) and IUG (ancient Latin). It means that the light in lovers' eyes is eternal at the moment of first meeting. After the passage of spring, summer, autumn and winter, the memory of mountains and lakes may be blurred. Only the first meeting lasts for a long time, and it is a lifetime.

As a practitioner who proposed to customize and open wedding rings earlier in China, a team of designers and plate makers from Zhi Zhi was established in Hong Kong, with more than 30 years' experience in jewelry design and production, and devoted to designing their own wedding rings for more newcomers.
