This morning I cried uncontrollably in my dream. It was because I heard a line from an ancient poem. I desperately tried to memorize it. Then I quickly searched and completed it. The line is: Who first saw the moon by the river? When did the moon by the river first shine on people? I don't know why, but I felt so sad. This line is so well written. The moon in the picture was taken during my visit to Dubai 2049.
