尘陌路笑忘书

'On Dusty Roads Laughter Forget Books' is quite poetic. 'Mò lù' refers to streets filled with dust from busy travelers (paths in life), 'xiào wàng' is laughing or even mocking the hardships, 'shū' can refer to a letter or book. Thus, it signifies forgetting worries through laughter along life's dusty paths.
