我笑了眼泪都掉了
[wŏ xiào le yăn lèi dōu diào le]
'Wo Xiao Le Yan Lei Du Diao,' translating to 'I smiled until tears streamed down my face,' conveys a bittersweet emotion - there can be joy with underlying pain, or vice versa. Those choosing it may want to share moments where strong emotions led to laughter and tears at the same time.
