I always think:

    Art is the world of the world. It provides a way to present clearly the unclear thought in your mind, also a stage to present unclearly but deeply the clear but simple thought in your mind. I’m interested in various kinds of art, such as music, painting/drawing, and seal cutting.  Ever since I met a brilliant and gifted artist/teacher, Li Daqiang, I have fallen in love with Line Drawing. This may be because it closely resembles a computer program, which can display images based on dots and lines. I love being able to translate what I see or imagine into lines, instantaneously transforming 2D into 3D.
