I will discuss the challenge posed by the LHC results, including the 750 GeV excess.

I will review the experimental and theoretical status of the so called XYZ spectroscopy of exotic hadrons with particular attention to open questions and most recent findings. The existence of seemingly contradictory pictures to explain their nature partly reflects the itricacies of non-perturbative QCD.
