童年的笙箫渐行渐远记忆的沉淀落满尘埃
[tóng nián de shēng xiāo jiàn xíng jiàn yuăn jì yì de chén diàn luò măn chén āi]
Meaning 'The reed-pipes (a traditional Chinese wind instrument) of childhood are fading away with memories covered by dust'. This expresses nostalgia for childhood, feeling that those innocent times are long past, far away, and only left as buried deep in one's memory.
