別路雲初起，Colorful clouds drift above when off you set, 

離亭葉正稀。faded leaves fall where the gazebo on sight.  

所嗟人異雁，Lamenting why are we not like geese,

不作一行歸。traveling to and fro together in flight.                          

PS It is said the impromptu farewell poem for her brother was written by an anonymous seven-years-old girl in front of Empress Wu Zhao.
