Nearly 30 years ago, the late poet Nguyen Trong Tao wrote such poems on the night he had to leave Hue. Looking at the Perfume River from the top of Kim Phung mountain, he did not often let his soul "stranded" in Hue. I have somewhat understood the sadness of the poet when I myself let my soul run aground between the green river and the green mountain, among the floating clouds on the top of Bach Ma.
