No Room For Growing

I found this location at Shipaotai Park, Shantou, China, on 15 Oct 2016.
I was fascinated to note the tree has grown through the damaged window of the building.
To me, this is a wonder of nature. But what puzzled me was the other window added a new metal grill. Photographically, from my vantage angle, is an interesting composition I would to capture the image. The touch of green has also added pleasing colour with a good framing. The peruse of such scene lead to my orientation of capturing this image without any other doubt.
