Yin Ling is a Vietnamese Chinese, who ties to Vietman and China by blood and by consanguinity. Vietnam was a French colony for centuries and suffered from vietnam war. That situation makes Yin Ling's words full of images of war, pathetique, and unable to be back home. The metaphor of river implies vivid images of "origin", "time", etc. So that is an appropriate point of view to explain the self-position in Yin Ling's poems
