The name of the Back to Back 生生不息 series was from the meaning of “continuity”. In the ancient Chinese heritage, it meant that everything continually reproduced, regenerated, and changed. The moment of renewal is the beginning of the other generation. It goes round and round and circulates in this way. Back to Back series design was based on the repeated contrasts of patterns in the mug bodies, delivering the messages of respecting nature and valuing all kinds of species.
