匣与桔
[xiá yŭ jié]
'Xiá yǔ jú', meaning 'box and tangerine/orange', seems rather abstract but might be alluding to two things coexisting harmoniously despite seeming unrelated - similar themes can be seen within classical oriental philosophies; alternately, since both words can have symbolic meanings within traditional culture, it might refer to preservation (of memories, emotions, heritage, etc.), or sweetness in small packages.
