One day, Gao Yuguan asked Chang Yupei: "Do you know what nonlinearity is?" Chang Yupei stopped what he was doing, turned to look at Gao Yuguan, and replied with shock in his eyes: "Brother... When did I become so smart?" Gao Yuguan touched Chang Yupei's head and replied with a smile: "You are just very smart, otherwise why would I like you so much~ I don't like stupid kids~"
"Nonlinearity refers to a mathematical relationship between variables that cannot be represented by a straight line and manifests itself as a curve, surface, or interaction that results in the whole being not equal to the simple superposition of the parts."
"Oh, I think I understand."
"Perhaps our encounter was caused by non-linearity~"
Intention: Let nature take its course and govern by doing nothing
