One of the works in the series of "three-dimensional calligraphy", it aims to show the formal and inner beauty of Chinese characters in three-dimensional form. "Mu 木" reduces the abstract form of Chinese characters to a vigorous growth of trees, preserving the essence of seal script. The spelling game of "Two more trees (Mu 木) come to the woods (Lin 林)" and “Three more trees (Mu 木) come to the forest (Sen 森)" also bring interest to the serious Chinese characters, and the "Mu" frame with the function of hanging clothes is also full of poetry and vitality.
