No one can solve the suffering of lovesickness. What do you mean, sentimental tears flow eastward?

Literally, it can be seen that this is a straightforward love poem. Lovers are far away from Qian Shan, which is the pain of parting and missing. Affectionate tears are naturally painful tears when you miss your lover. "East Flow" describes these tears as vast and uncontrollable as rivers (rivers in China generally flow from west to east due to the differences in topography), which vividly reflects the pain and affection of the poet and his lover's separation.
