When I left a messege to Ziyang behind his article on his dad's orange tree, I had no impression on him. since I had never seen a tree of orange before,  I expected to see a picture of the orange tree when I opened this article. but there was no pictures. then I said this to him.

later on he answered me he would take some pictures for me once he go home again.

I can not remember when we talked about this. even I can not remember this request any more. he must forget his promise.......

luckily, orange is still on the tree.

and also leaves

this is a productive tree (600-700 jin a year).
