[1]When we talk about paintings, we usually think of pictures on paper.But recently, a college student brought us another kind of painting.She paints animals and birds on the bald (光秃的) parts of trees and tree holes! Thanks to her paintings, an old street in Shijiazhuang, Hebei Province has become her exhibition hall.
[2]The ____________ of these paintings is Wang Yue, a college student from Dalian Polytechnic University.She got the idea of painting on trees while she was visiting her home for Spring Festival.“In winter, the bald parts of trees look really ugly, so I wondered whether painting pictures on them might help cover some flaws (瑕疵) of the city.” Wang said.It is also part of her graduation (毕业) work.
[3]“Painting on a tree hole is not as easy as painting on paper.I had to think about the shapes and sizes of the tree holes and adjust (调整) my designs accordingly,” she said.“Before I began, I had to clean off the dust (尘土) from the tree holes first.”
[4]Her first painting was some clouds, but many people couldn’t understand it.After that, she began to paint animals.

Where did Wang Yue paint in her hometown during the Spring Festival?
