  I discuss the production mechanism of hidden-flavored hadrons at high energy.
Using $e^+e^-$ collisions and light-meson pair production in high energy
exclusive processes, I demonstrate that hidden quark pairs do not necessarily
participate in short-distance hard scattering. Implications are then explored
in a few examples. Finally, I discuss the production mechanism of $X(3872)$ in
hadron collisions, where some misunderstandings have arisen in the literature.
