想想想想到彻夜难眠念念念念到痛彻心扉
[xiăng xiăng xiăng xiăng dào chè yè nán mián niàn niàn niàn niàn dào tòng chè xīn fēi]
'Thought leads to sleepless nights, yearning pierces through my heart deeply', this expresses extreme emotions where thoughts result in insomnia and yearnings bring great emotional agony, reflecting profound attachment or sorrow.
