摘　　要：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.I discuss the production mechanism of hidden-flavored hadrons at high energy.
