In QUEST: Where Heaven and Man Meet, Yu-li explores his deep thoughts on the relationship between heaven and man, as well as the ‘Universal Language’ bridging the two. Applying the fundamental elements of the Universal Language – namely the dot, line and plane - the artist explores the limits of man's existence.

Sun Yu-li’s creative mentality and his works are expressed in the most primitive symbols and diagrams representing the finite and infinite. He believes that all things in this world can be presented as patterns. From shooting stars in the galaxy to the trace of wind left behind on the sand, the development of material and life are all manifested in the form of patterns. In space and time, the conflicting pounding of finite and infinite represents the continual changing of state.
