“In order to reflect the damage of factory waste smoke and industrial construction to the natural environment such as blue sky and plants in the process of industrialization, the contrast between the beautiful natural scene and factory pollution arouses people’s reflection on the disadvantages of industrialization and arouses people’s awareness of environmental protection. Everyone protect the environment.

The work started to be conceived on December 5, 2022, and suitable ginkgo leaves were selected as materials in the botanical garden, and the creation began. Carve and cut the leaves with tools such as a carving knife, retain the middle and lower parts of the leaves, and engrave the upper part as a scene of factory exhaust smoke and gas, and use marker pens for details. The whole work is based on white paper, and the blue sky and white clouds are drawn with colored pencils and highlight pens. The leaves are placed on the bottom. The shadow of the leaves represents the black smoke emitted by the factory. The work is named after “leaf”, which is a homonym for “industry”, implying that we must not forget to protect the “leaves” when developing “industry”. After three revisions, it was created on December 10, 2022.”
