白瓷为纸载往昔青花作笔写回忆
[bái cí wéi zhĭ zăi wăng xī qīng huā zuò bĭ xiĕ huí yì]
Translated as 'Use White Porcelain as Paper to Hold the Past, Let Blue and White Porcelain Pens Write Memories.' It evokes poetic imagery of delicately recalling past events through cultural elements specific to Chinese art forms, indicating nostalgia.
